In his native HVZ many good models of bicycles were produced. Among them can be identified road Ukraine and tourist Sputnik. Maybe someone has such a bike, and you are sorry to throw it away. Moreover, you can upgrade this bike and not spend money on buying a new one.
In the process of modernization, it makes sense to leave only the frame and fork from the native bike, the rest of the body kit will be changed. Sputnik’s frame is lightweight and it is possible to put 37 mm thick rubber on the rear wheel, compared to the frames of sports models. You can also leave the rear wheel hub.
Details on domestic-made bicycles are becoming increasingly difficult to get in our time, in view of the fact that KhVZ has not been working at full capacity for a long time.
First of all, we change the carriage from the wedge to the square. Change the connecting rods, sort out the carriage, cups. We make a new thread. Lubricate it with oil. Insert the cartridge. We assemble the connecting rods and gearbox. Everything takes about an hour.
If you have the means, we put a cartridge and a foreign carriage, for example, Shimano company, whose 24 speeds will give you the opportunity to climb any hill.
We also take the chain from Shimano or KMS.
Imported switches, in comparison with domestic ones, have an advantage in reliability, aesthetics. For example, the Shimano switch will not allow you to jump off the chain and change gears will be just a click away, and not moving the slider back and forth, adjusting the gears.
With a large number of speeds, disk-shaped circuit protection will also be necessary.
Bicycle rims with brake pads must be double.In the case of single - the rim will bend over time, an eight is formed and the brakes will stop working. The same is true for disc brakes. In addition, the double rim is more reliable.
If we want to get a racing bike, we put narrow rims on which then we put narrow racing Slim tires. The bike will ride fast on a flat track. But it will be extremely difficult to wade in urban pits or rough terrain. In this case, put a half-slim tire and a rim for it, respectively.
The standard steering wheel for Sputnik is bent, like racing bikes. However, if you plan to be in the saddle for several hours in a row, such a position will make the trip tiring. In this case, it is recommended to put a direct wheel, even with raised handles like road bikes. So your back will be flat on the road, and you will be less tired.
A saddle for a sports bike is chosen without shock absorbers. It allows all energy to be transferred to speed. But your fifth point will feel the consequences of such a ride very strongly. Therefore, if you do not need to participate in races, you should pay attention to soft saddles with double shock absorbers. The same is true for the front fork. If you want a comfortable ride over bumps, there is an option to install a fork with shock absorbers, like mountain bikes.
Standard crimp brakes can perform poorly on wet roads. There will be poor contact and the braking distance will increase. In order to rectify the situation, one or two wheel disc brakes are used.
It is better to buy pedals iron, with a relief. The plastic will break quickly and will be in poor contact with the leg. As a result, you will spend more effort on driving than you could. To this end, you can get a pair of good sports shoes for cyclists.
For a comfortable ride, it is recommended to purchase glasses from the sun and wind, protection for trousers if you ride in trousers, and a drinking system that allows you to drink water without taking off the road.
That's all. If you followed the recommendations, then you have a wonderful bike that will be either the fastest or the most comfortable depending on your preferences. Riding it will give you many pleasant minutes.
