Modern bicycles (high-speed, double-suspension, mountain, hybrid, highway, etc.) have a beautiful and graceful appearance. They consist of complex mechanisms (disc brakes, carriage, shock absorber, cassette, etc.), which significantly increase ride comfort, but need constant care. In order to repair any part, you need to know what it consists of and how it works.
From this article you will learn about the comprehensive repair of the Stealth bike with your own hands, after which you can service it yourself. We will also discuss several complex mechanisms (bicycle cassette, carriage), how to repair them and what tools will be needed for this.
Rear wheel repair
The rear and front wheels are important components of a bicycle. Why? When driving on uneven surfaces (pits, mounds, stones), it is the wheels that take most of the hits. Therefore, timely service helps to maintain not only comfort while riding, but also speed, which is no less important for every cyclist.
In order to repair the rear wheel of the Stealth bicycle (with your own hands), you need to stock up on the necessary tools. For this we need:
- wrenches (from 8 to 16);
- set of hexagons;
- pliers;
- screwdrivers (Phillips and hex).
One of the main problems of the rear wheel is an uneven rim (figure eight). Every cyclist faces this difficulty. Why can a wheel become a figure eight? As we learned, more than 85% of all hits take wheels. Most of the load falls on the rear wheel.
To align it, you need to install (perpendicular to the rim) two cotton matches, and using pliers to weaken or strengthen the knitting needles. For example, if the rim is curved to the right, then the knitting needles on the left should be tightened, and those on the opposite side should be loosened.
Bicycle cassette
The cassette consists of several pairs of stars that are mounted on the sleeve, namely the drum itself. Often, the cassette contains 7 gears that are mounted on a spider. But on some bicycles, for example, on hybrids, there can be from 8 to 11 stars, which significantly increases the acceleration of the bicycle.
Repair of the Stealth bicycle cassette (with your own hands) consists in timely cleaning of each star from dust and deposits, as well as monthly lubrication of parts. You can clean the sprockets with a toothbrush, as it will help you get to hard-to-reach places. As for lubrication, you should not use solid oil, petroleum jelly, or another similar tool. The most optimal substance for these purposes is ordinary engine oil (transmission or motor). If finances allow, then you can buy a special solvent for cleaning stars.
Carriage
As you know, there are only a few types of bicycle carriages - cartridge and integrated. Both varieties consist of industrial bearings, which are connected to the shaft and rods of the connecting rods using a spline connection. In fact, the cartridge carriage cannot be disassembled, but if it is integrated, then it lends itself to such manipulations.
When disassembling, you will stumble upon two exactly the same cups that contain industrial bearings. Pay immediate attention to their location. After cleaning and lubricating the two cups and the carriage tube, it is necessary to install them in the places where they stood. As a rule, the first cause of breakage is the incorrect position of the thread.
Tools with which you can maintain the carriage:
- screwdriver;
- puller for mechanisms;
- special key for crank release;
- slotted keys;
- set of wrenches.
Before you begin to remove the mechanism, you must secure the bike so that it is stationary. After this, pull off the plugs that are on the connecting rod itself, unscrew the fixing bolt, remove the connecting rod and release the axle.
Repairing the Stealth bicycle carriage is quite simple. If it is cartridge-mounted, then it cannot be repaired; it is best to change it to an integrated one. In this case, the carriage can be serviced for a long time.
Stels adrenalin
We examined some of the features of repairing a Stealth bike with our own hands. Now let's look at a specific bike model, namely Stels Adrenalin.
The frame of the bike is made of aluminum alloy. This model cannot be called light, because it is more designed for men than for women. Depreciation leaves much to be desired, but if you use this “bike” only for short distances, for example, bike rides around the city or to and from work, then it will be quite enough.
Do-it-yourself stealth bike repair is no different from fixing other models. All the same mechanisms and structures that can easily be removed and replaced if necessary. Almost any oil can be used for lubrication, but it is best to buy special greases that provide more reliable protection against corrosion and other contaminants.
What roads is Stels Adrenalin designed for
Due to poor depreciation, this “bike” is intended only for urban roads at an average distance (up to 50 km per day). The front fork has the property of quick wear, but if you replace it with a more powerful one, it can significantly extend its life. At Stels Adrenalin, the front and rear rims are reinforced. Therefore, for some time you can not worry about their curvature.
In order to repair a Stealth bike with your own hands, you need a little knowledge and all the necessary tools.
Conclusion
A bicycle is the most environmentally friendly mode of transport. Many argue that a daily trip on it improves well-being, raises the tone and helps to always remain in excellent physical shape.
Repairing a Stealth adrenalin bike with your own hands is not as hard as many people think. If you have at hand all the necessary tools, as well as knowledge of exactly how to service it, then this work will not seem burdensome to you. The most important thing is the timely maintenance of the bicycle (lubrication of all available parts and mechanisms, adjustment of brakes and speed switches, alignment of the rim, etc.), and then you will not have to repair it soon.
