Hvz bicycles DIY repair

In detail: bicycles hvz do-it-yourself repair from a real master for the site my.housecope.com.

Breeding "crocodiles" on the basis of HVZ bicycles originated in the 60s and remains popular to this day. The number of spare parts and new fashion trends in the development of this fascinating creativity is increasing every year.

Modernization of bicycles based on the released models "Ukraine" "Sport", "Tourist", "Champion", "Start" by the Kharkov Bicycle Plant.

This factory began producing bicycles in 1923. The first craftsmen who set up production came to the factory from Riga. Since that time, the production of bicycles began to increase annually until the Second World War. Millions of bicycles were produced in the pre-war years.

The interrupted production during the war was restored from June 1945. They began to produce women's and children's bicycles, which all improved every year and both the demand for them and production increased. High-end sports models were produced.

Obviously, the gift of modeling and construction is inherent in everyone who dares to change their bike. What crocodile masters strive to improve. What kind of crocodile they want to get out of their bike.

Initially, it seems that improvements were required for the bicycle wheels, which bent into eight in a serious accident. Then there was a need for improvement in racing sports bicycles, in which each inventor strove to increase the speed characteristics.

Firstly, when you read crocodile blogs you can already reap a lot of benefits for yourself. After all, you, as a cycling enthusiast, know what characteristics you will achieve by replacing spare parts.

Improving speed performance, reducing susceptibility to obstacles on the road, cross-country ability in hard-to-reach mountainous areas. Masters of their craft will certainly strive to educate dummies how to sculpt a cool bike out of an old shabby and well-worn bicycle.

Even engineers in the field of bicycle building are guided by the advice that crocodile breeders give each other, it's like testing prototypes before mass production of a serial model.

Steering wheel
Brakes
Front and rear bushings
Rims
Knitting needles
Saddle
Tires
Installing the motor on the bike.

The parts that are usually sold now are made in China.

The following are subject to replacement for the upgrade:

wings,
horn bells,
trunk bags,
steering wheel bags,
lanterns,
mirrors,
front and rear bushings.

If you need tools for crocodile practice, you need to purchase a special tool kit. And in the service center, you can order services for lubrication, adjustment, if you cannot do something yourself.

Collective farm tuning, such an expression stuck to bicycles pasted over with various bright stickers, with an electrical tape wrapped around the steering wheel, wound on the spokes with multi-colored wire, in general, that modernization that does not improve speed or physical and technical indicators, but simply changes the appearance of a familiar bicycle.

But installing headlights on a bicycle, for example, or installing diode lighting, is no longer considered collective farm tuning. And also the installation of bicycle computers, rear-view mirrors, replacement of the steering wheel, wheels is not a collective farm tuning, as they are a functional improvement. Bicycle upgrade should not only make it stand out from the crowd of brands of the same name, it should increase its performance, endurance, capacity, durability.

What can you say to beginners crocodile breeders.You can browse through a bunch of crocodile forums, but until you start making your first crocodile with your own hands, you will not understand anything. And even if you chose old trash as a basis, you can make a real swallow with the help of refinement.

It may very well be that you have an old Soviet bicycle lying around on the mezzanine (in the closet, in the garage, in the country house, ...). It may also be that right now you are diligently paying interest on a loan for a new yacht and there is no longer any extra cash left for a new bike. Or you are purely aesthetically pleasing to the look of the bicycles of that era. In this case, you have an amazing opportunity to bring your old bicycle back to life and flaunt the streets of your hometown, the fields and villages of your home country on a unique machine!

As a rule, they are engaged in the revival of old bicycles of the HVZ (Kharkov Velo Plant) production: Sport-Highway, Start-Highway and Champion-Highway, Sputnik, Tourist, Champion, Starton. The revival and modernization of other bicycles or bicycles made in Russia, Belarus, Ukraine during perestroika is also possible, but it is of less interest due to the poorer quality of the “source material”. However, the only limitation is your desire.

First of all, since the bicycle has survived to this day since its release, for example, in the 60s of the 20th century, this already speaks of its strength. Modern bicycles with aluminum parts are lighter but wear out much faster than their steel predecessors.

Further, the degree of modernization required depends on the condition of the particular bike and your desire to modernize it. The better the initial state, the less you need to change. In most cases, the wheels are completely changed - the technologies do not stand still, and they are very susceptible to wear and tear on the rim, they are hardly preserved in good condition. The greatest difficulties are caused by the carriage and shifters.

A correctly assembled carriage and connecting rods on the wedges do not loosen up, do not play, no matter what those who did not really use them say on the forums. Straight arms decide everything. But the carriage is one of the most worn out units, so it makes sense to replace it with a modern cartridge one. This is where the difficulty arises - the fact is that at different times different manufacturers made carriages of different diameters with different types of threads. It is not at all a fact that a modern cartridge can be installed without additional efforts. It is often necessary to cut the thread with a special tap. Sometimes special adapters are made from a larger diameter to a smaller one.

Difficulties with shifters are as follows. These are sports bicycles or those close to them with a curved "ram" road handlebar. Mountain brake levers and shifters available in almost every store are not suitable. The most convenient way to use the combined road monoblocks is shifter + brake lever. But they are expensive, and usually they tend to upgrade the bike with minimal investment. In addition, bicycles of those times were supplied with 3-5 stars, and now less than 7 is difficult to find. Hence the need to either unbend the frame, or select shifters for working with a ratchet for 5-6 stars, or come up with original combinations of popular components for mountain workers.

Sometimes, in addition, they weld on the frame to attach V-break brakes, bottle holders, mounts for additional switch cables. This is already a matter of taste / needs. For example, vibrake brakes are easier to find than suitable U-shaped tick brakes if family members have fallen into disrepair. If there is an opportunity and does not care too much about the appearance, then it is easier to weld the mounts than to look for cantilever brakes with long “legs” (the distance from the mount to the rim is more than 5 cm.).

The result of a neat upgrade looks very attractive (the grace of a thin steel frame and narrow wheels) and rolls better on tarmac than an MTB.Of course, the bike is not for competition - sports and extreme loads require a completely different technique. As a rule, such bicycles after recovery are closest to the class of tourist (touring, "touring") or road bikes for training (weight from about 11kg). However, variants of a city bike with a high seating position and a straight handlebar are also not uncommon.

These upgraded bicycles are often referred to as “crocodiles”. Why it is so difficult to say. Maybe the name came from the fact that HVZ bicycles, popular for modernization, were originally green. Or the first ones restored were so scary. A very plausible version is that this is how FIDO called any old-school bike modified by the owner to something unique (now it would be called a custom bike), later the name spread to all modernized bicycles.

It may seem that the restoration of old bicycles is exclusively domestic entertainment. Still, HVZ. but as you saw in a couple of links above, English-speaking countries are also busy reanimating old bikes and customizing.

In conclusion, a few examples of "crocodiles" describing the process of their modernization.

The main stages of setting the rear derailleur, a detailed description of possible problems and features.

On the one hand, absurd in essence, but on the other - a work of art, the old bicycle advertisement is worthy of attention and detailed study.

The second name for the cycle track.

I would like to say right away that I am not the author of these works, I just found articles on the Internet, where I don’t remember specifically, but they helped me.

The topic of reanimation of products of the domestic bicycle industry comes up with enviable regularity. But first, a little excursion into history. As you know, throughout the USSR, one class of single-speed bicycles was produced - entry-level road bicycles, and several closely related multi-speed bicycles, which were considered the height of engineering thought, but in fact were foreign developments of the mid-50s of the last century. Only a few representatives of the latter are suitable for alteration.

There were two branches of bicycles - tourist and road. The first is represented by "Sputnik" and later by "Tourist", the second is the well-known "Start-Highway" and the so-called special order - "Sport", "Champion-Highway", etc. I must say right away that practically nothing from the standard hitch can be used ... We are left with only the frame and the fork. The best ones are for road frames, more or less for Sputnik, while Tourist is actually made of “water pipes”.

Really, it makes sense to invest only in the "special order" and the old "successful" frames "Start-Highway", because at the end of the 80s the quality of the latter dropped dramatically. "Sputnik" is also of a very mediocre quality frame, but it has an indisputable plus in front of road frames - these are wider rear stays, allowing rubber up to 37 mm wide (for pure road frames, the limit is 32 mm).

A few words about the hinge plate of the X-BET-3 brand. The whole world uses inch standards for threads and diameters for bicycles - this is how it happened historically. But the USSR has always stood apart, so all foreign developments were redrawn for metric threads. Hence all the problems. Nothing is suitable for our business, only the frame, the fork, as well as the stem and the steering column will remain - due to their aforementioned non-standard.

In principle, it is possible to replace this too, but this is a very expensive operation. Moreover, other columns work quite well for themselves.The exception - that is, what can be kept - is some "custom" components. These are bushings, as well as aluminum systems for a square (compatible with imported carriages) - milled Izhevsk and old Kharkov ones. Cast Penza ones are not good - they break. Also, do not use Penza offsets - for the same reason. Casting is unusable. Better iron HVZ, although it is unrealistically heavy. Wheels, brakes, cables, shirts - everything will not work. It is probably unnecessary to talk about the system, the carriage and the pedals. The steering wheel, brake levers, shifters are just uncomfortable. If you really want to, you can, of course, leave the bushings and even the brakes, but the HVZ bushings are inferior in resource even to the five-dollar Taiwanese ones, and the brakes are very difficult to set up well. So we only leave the frames, fork, stem, steering column. Saddle and seatpost available on request. It does not affect the maximum speed, but they will provide an extra kilogram and a half.

The most ordinary bicycle "Tourist" of the Kharkov Bicycle Plant with four gears. The front fork, of course, is rigid, there were no others in the USSR at that time. And in the world they were still very rare. Compared to the then single-speed "road" bicycles, this was a thing, although knowledgeable people argue that compared to the Start-Shosse bicycles of the 70s, these bicycles were already significantly inferior both in weight and strength (in terms of running characteristics - in definition).

So, let's move on to the bicycle repair method - "Tourist", "Start-highway", "Sport":

Due to the lack of parts (the plant in Ukraine has not been operating at full capacity for a long time), and those parts that have been produced in crumbs in recent years are of disgusting quality, but at a price they are not inferior to imported ones.

First of all, we leave the carriage shaft of the "wedge" system, this is a relic of the past and go to the carriage shaft "square". All new and modern systems from leading manufacturers are designed for "square". To do this, it is necessary to install the "cartridge" shaft (it is better on industrial bearings its resource is very long - from 3 to 10 thousand km).

1. When buying a set of front connecting rods, the first thing we do is determine (number of sprockets):

There will be road stars
or combined.

2. We measure the seating depth on the connecting rod from it will hang the length of the carriage shaft "cartridge".

Removing the connecting rods
We disassemble the carriage, turn out the cups.
Take a tap 35 × 1.37 - 24 and cut a new thread.
Lubricate the new thread with liquid oil.
We screw in the "cartridge" (Industrial Bearing). Shimano UN-25

4. Install new connecting rods. The whole procedure takes about an hour of work.

5. We adjust the gear shift.

If funds allow, we install a carriage cartridge and a foreign-made system. It could be the same Shimano Tourney, Altus or Sora. With such gears, you can already quite safely go to a decent rise.

Since the bike is quite playful, it is better if the chainrings have the following set: 48-38-28 (30). When changing the connecting rods, keep in mind that there is a certain development on the parts you have left (the chain is stretched - the rear sprockets are sharpened - the rear caliper is worn out), it all depends on the mileage and the intensity of use.

If the chain from "Start" can work at the very least on a five-fold ratchet, then a narrow imported chain (width 7.1 mm) is already needed for 6-7 stars behind. We used a Shimano UG50 or UG51 5/6 speed chain. 6/7 speeds - IG-31 Acera or IG-51 Alivio. 7/8 speeds - IG-70, IG-90, HG 73 or HG93 LX / XT.

If there is a great desire to save money - leave from "Start". What should be borne in mind - both bushings from "Start-Highway" and unpretentious foreign ones have very primitive protection from dirt and water, therefore, with intensive driving, you will have to sort out the bushings a couple of times a year. In addition, the eccentric fastening of the rear wheel is not very reliable on this hub.

Or we buy a bushing from a foreign manufacturer.The most common bushings are for the threaded connection of the rear sprocket block and for the cassette. Cassette bushings should be considered more reliable.

If you don't have enough money, bet any. If so, start with at least Shimano TY40 or Altus. Russian duralumin are too fragile, iron from HVZ is quite reliable, although extremely primitive.

When installing, pay particular attention to the limiters of the switch movement (such bolts). A favorite pastime for unadjusted derailleurs is to fly into the spokes at the most inopportune time. It should be borne in mind that if you purchased a ratchet or cassette with a large rear sprocket for 34 teeth, you need a uniquely foreign derailleur adapted to work with such a sprocket. Outwardly, such a switch has rollers with a larger diameter.

One of the most essential points. There is no need to spare money here. The choice of 28 ″ rims in Moscow is not limited, you can buy almost any rim or order the right ones and wait a while. We definitely do not take the products of Russian factories. The extras they produce are of disgusting quality.

Bicycle rims "Tourist". First, it seems that they no longer exist in nature. Secondly, even if they stayed somewhere, it is better to invest in foreign double rims. Single and double - foreign. Avoid using narrow clincher (made especially for narrow racing tires) rims. In this case, you will be forced to use only racing tires (622-20 / 23/25), and this will greatly affect the bike's flotation.

Rims with a width of 18-21 mm are suitable and preference should definitely be given to double ones.

During operation, a bicycle, like any mechanism, requires personal care. Of course, it is not always possible to take your iron horse to the workshop, and is it worth it, when in 80% of cases, you can repair the bike yourself. In the remaining 20%, bicycle repairs in Moscow, or in another large city, can be entrusted to an experienced specialist, for example, if, during an unsuccessful collision, mechanical damage to the frame and other parts has occurred. After the purchase, it is important to take care of the parts that experience the most friction.

After buying a bike, what matters is the initial treatment of all parts subject to the greatest friction. Note that places greased with grease or oil accumulate dust and dirt, which destroy the mechanism, working like an abrasive mass. Chains, bearings, and other parts simply wear out faster, due to the fact that the coefficient of friction increases. In this case, friction can increase several times. It all depends on when the bike was last serviced and repaired.

In order to do your own bike repairs, you will need to rent a room. You will also need a whole bike repair kit:

bicycle repair keys;
Mallet;
Several pliers;
A set of various screwdrivers with a spatula and a cross;
Scissors and clamps;
A set of end caps;
Bicycle repair rack.

You can buy a bicycle repair tool both in a regular bicycle parts store and online at specialized sites.

If you learn how to repair a bicycle with your own hands, then you can open your own workshop. So bicycle repair is popular in various cities of Russia and Ukraine. Basically, bike services are opened in large cities with a population of 200 thousand people or more. It is most profitable to open bicycle repair shops in St. Petersburg, where groups of specialists work in their narrow focus. Some craftsmen are engaged in the repair of sports bicycles. Others are working on the restoration and repair of old bicycles. Still others are directly involved in the repair of mountain bikes with their own hands in mountainous areas.So there are many bicycle repair shops in Stavropol, located in the administrative center and large cities of the region, specializing directly in the repair of mountain bikes. Similar highly specialized workshops are located in places with variable (flat and mountainous) terrain, for example, numerous bicycle repair shops in Krasnoyarsk, located in the cities of the region, as cycling in the wild is popular in this region.

Where to open a bicycle repair shop. Bicycles for children of various ages and for adults are being sold in large quantities in various cities. Depending on the type of product sold, offer the appropriate type of service, for example, repair of children's bicycles in Moscow. Considering that bicycles for children are bought in large quantities, the repair of children's bicycles can become your niche in the business. As an example, you can watch the video "Do-it-yourself Stork bike repair" as a variant of the developed system of maintenance and repair of tricycles.

Cycling tourism in Russia is popular in various regions, and many amateurs are fond of their hobby not only in the warm season, but also in autumn and winter, respectively, repairing bicycles for tourists will be a profitable business all year round. However, study your market for services, supply demand, direct and indirect competitors. In a word, not only a business plan, for example, for the repair of bicycles in Yaroslavl, taking into account the costs and a complete analysis of the market.

After you analyze the market for bicycle repair and customization services, you can decide on the cost of services. To begin with, set the prices for bicycle repairs a little lower than average, then after you unwind, you can raise the cost of the services provided to profitable ones.

If you want to go into business, then do not forget to purchase additional equipment for repairing your bicycles. We recommend purchasing:

Chain squeeze;
Carriage puller;
Ratchet and socket wrenches;
Remover for brake disc cassette (for repairing shimano rear derailleur);
Key for removing and installing spokes;
Pump;
Set for bleeding the brakes, hydraulic;
Oil syringe;
A glass for measuring oil;
Spare set of tubes and tires.

To run a successful business, you will not only need to spend your capital on a bicycle repair tool, but also lubricants, solvents and other kits.

Liquid for lubricating springs of gear shifters, chains, pedals (for lovers of cycling on broken roads and bumps).

Fluid for grease, forks, oil seals, air shock absorber swabs.

Fork oil;

Brake oil and hydraulic fluid. If you buy a liquid for yourself, then buy one type of lubricant for repairing high-speed bicycles, if you open a workshop, then buy both varieties.

Cleaner for brakes and transmissions;

Lubricant for fork springs, shifter bearings and other parts.

That is what is meant by wear and tear on the bike. Every detail that makes up a part, regardless of the type, wears out over time.Do not think that the frame is least exposed to stress and friction. As with any metal, steel on a frame becomes obsolete over time, especially on those bicycles where there is no shock absorption. The main accumulation of "fatigue" occurs at the rear suspension pivots. How does "fatigue" occur? this is expressed in deformation, cracks, ruptures, in the joints of the nodes. Therefore, bike frame repairs are as common as other parts.Most often, deformations and cracks appear in places where the weld seam passes, on the carriage and steering parts, as well as on the feathers and landings of the wheel bushings. You can watch a video on repairing the rear carriage of a bicycle.In order for the frame to last longer, you simply need to drive carefully.Before you start repairing the frame, you need to completely clean it of dirt. If you ignore this part, then you may have other problems with worn materials. Plus, on a dirty bike, it's hard to evaluate performance. First, wash the frame under a gentle stream of water, and remove any dirt streaks with a brush or cloth.Before starting the repair, diagnose damage to the rear and front suspension joints, welds, head tube, bottom bracket.Even with the smallest damage (cracks, breaks), the frame must be replaced. If the diagnostics showed only scuffs, then a cosmetic repair of the bicycle frame is carried out. With the help of special tape and paint, scratches are removed. To see how this is done, watch the DIY Bicycle Repair video.

Carriage. There are no technical instructions for repairing a bicycle carriage, but it is also changed in workshops when it is worn out or mechanically damaged. It is not necessary for a biker to seek help from a master; it is not difficult in this regard to repair the bicycle carriage with his own hands.

The two types of carriages (cartridge and integrated) consist of two cups. Each has its own bearing. When disassembling and replacing the carriage of a Stealth bike during repair, it is important to remember where both the one and the second carriage cups are located. To understand the mechanism, watch the video on the construction and repair of the bike: rear hub.It is a connected mechanism of plate and cylindrical compression plates. There are at least three rows of bearings, two are installed on the housing, the third on the drum.Once a month, during intensive driving, it is advisable to lubricate the ratchet with a special oil, after removing the old grease with a solvent.Additionally, watch the video "Bicycle Rear Wheel Repair". The front wheel is repaired in much the same way.Repair of the derailleur on a bicycle consists of diagnostics regarding the frame, adjusting the screws, checking and adjusting the cable tension. Additionally, the owner or technician should lubricate the torsion and tension springs of the rollers. Repairing a bicycle's rear derailleur and front wheel mechanism will vary significantly.Additionally, you can watch the video "DIY Stealth Bike Repair" on this topic, where special attention is paid to the repair of the rear derailleur on the bike.The safety of the biker primarily depends on the high-quality operation of the brake system, therefore, its serviceability must be a prerequisite.Conventionally, the brake system is divided into hydraulic line calipers, handles.The caliper (caliper) are brake pads, and an aluminum body with a piston.The number of pistons is usually two, on high-quality sports bicycles it is four.Repair of hydraulic brakes on a bicycle is a replacement of worn-out pads, diagnostics of the state of the piston system, since depressurization of the pistons threatens to brake failure. Image - Bicycles hvz DIY repair

When checking the bike in motion, several points are established for repairing the brakes on the bike:

If the braking is insufficient, then the handle fails: there can be two reasons:

The pistons are depressurized or the pads are worn out.
In this case, the pads are changed and the brakes are pumped.
Prolonged braking will result in brake fluid boiling and complete brake failure. In this case, let the liquid cool down for a few minutes.
If the handle does not fall but the braking is weak then check the pads. Is there dirt under them?

Brake levers. They are represented by a body part, handles and a piston. Your task is to check if the handle is leaking and to check the O-rings for tightness.

Nowadays, an increasingly popular form of transport is great. Much has been said about its health benefits, and it is also a full-fledged vehicle in the city. The bike is comfortable, compact and does not require such financial investments as a private car.

In the old Soviet times, city bikes were almost the only option for traveling on two wheels. Now a dime a dozen is great, for every taste and color. Single-speed "bugs", similar to Soviet models, are still not the same. Are there still Soviet classics? Yes, full! And if an old model of the USSR suddenly stands idle in the garage, then it is worth doing the modernization of the bike with your own hands.

It is up to everyone to decide how appropriate it is to tidy up the old model on their own. And here it no longer depends on the fact that the great has lived for a good three decades (Soviet frames have been rolled over more than one generation), but on the scope of use in the future. So, for example, you should not modernize the Soviet classics for those who:

prefers to ride over rough terrain;
loves speed, lightness and off-road;
does not want to bother with the selection of new parts.

And of course, if the frame is seriously damaged, then it will be much safer to hand it over to scrap metal.

For quick and comfortable trips around the city, modernizing a simple Soviet bicycle is justified. The work will require financial and time costs - you will have to change the entire canopy, except for the fork and frame, and work on the appearance.

The appearance of the bike determines the color of the frame and wheels. Additionally, you can install colored tires, accessories and do light tuning.

We completely disassemble the bike before painting the frame. The work consists of stages:

Remove old paint with thinner.
Remove rust - there can be a lot of it on an abandoned Soviet bike.
Degrease all surfaces.
Apply the primer in several layers, let dry.
Apply paint from a spray can to the primed surfaces in several thin layers.
Dry in a ventilated and warm place. We observe accuracy and do not paint near fire and hot objects.

For aesthetic reasons, we reduce to zero the appearance of insects in the room - flies frozen in the paint will only spoil the view. The fork and frame are painted separately. Drawings on the frame are made using vinyl stickers or stencils.

The rims of the wheels are painted over in the same way.True, here it is necessary to protect the knitting needles and bushings from paint ingress - wrap them with plastic wrap.

Additional sheds, or how you can diversify the bike:

bright grips;
rearview mirror;
headlight and taillight;
analog speedometer, bike computer;
tool bag (Soviet style);
new fenders and mudguards;
flask and bottle cage;
step.

All this is widely available in bike shops.

Light tuning will add originality to the bike in the dark. In addition to standard lights, you can make the bike even more noticeable. The most important thing is that it is all very simple to do it yourself. So:

glowing caps on nipples - the simplest and cheapest solution, we buy several sets and change from time to time;
LED strips on wheels and frame;
disks-animators - exhibitions on wheel spokes; in motion they play with light patterns;
battery-powered Christmas tree garland.

In these simple ways, you can distinguish your bike from similar ones, as well as ensure your safety on the roads.

As a source material, we will take an old bicycle "Ural" and a high-speed "Tourist", which was newfangled in Soviet times. Upgrading the single speed model is easier, there is no need to fiddle with switches and shifters. However, if you wish, a high-speed bike can also be adapted to the modern way, the main thing is desire.

So, to modernize the old great times of the USSR, you will need:

replace the carriage and cranks with pedals;
go over the plug, replace the steering wheel;
put new wheels;
improve the braking system;
change the saddle.

Additionally, for the high-speed model, select shifters and install a new gear shifting system.

The carriage is the most important and first unit to change. It is impossible to find identical spare parts in our time, so you have to think about how to put the simplest and most affordable cartridge (closed) carriage.

To install the front system you will need:

redo the thread or install special adapters for a smaller diameter;
install the carriage and new connecting rods "under the square" with special pullers;
for a high-speed bike, we purchase cranks with a three-star system;
put new pedals.

Replacing the fork is the second most important task after replacing the carriage assembly. Washers and bearings may need to be replaced. In any case, a bulkhead is necessary at least for simple lubrication of the parts. First you need to properly disassemble the plug. It is not necessary to change the steering wheel, unless it is rusted or there is no desire to install a steering wheel of a different design. New rudders of the Soviet standard are now more difficult to find, you will have to wander around the shops where single-speed road builders and spare parts are sold.

The next step is to update the bike for v-brake. Today, this is the most common type of brakes on sale, as opposed to u-shaped caliper brakes - they cannot be found with fire during the day. And the efficiency of vectors will be higher. For installation on a Ural bicycle, special seats will need to be welded onto the fork. "Tourist" provides a v-brake on its frame.

Replacement of wheels. We choose double rims, so they will last a long time and not so often you will have to fiddle with eights (as opposed to single ones). What to find: 28-inch wheels with double rims. For the Urals, we choose a wheel with a brake sleeve. If there is none, you will have to install the bushing separately or put a regular wheel under the v-brake. And before that weld on the seats on the rear stays.

For a high-speed bike, you will have to change both the derailleurs and shifters. It is not difficult to do all this with your own hands, it is more important to match them correctly to each other: the 7-speed shifter must correspond to a 7-star ratchet. By the way, it is advisable to put ratchets on Soviet bikes, although you can also spend money on more expensive cassettes.

It is not difficult to modernize a Soviet bicycle for a modern one.To do this, you will need to invest in money and take the time to find the necessary spare parts with their installation, everything you need to paint the frame and forks and purchase accessories. The Soviet bicycle of our days will fulfill its intended purpose for a long time to come and delight others.
