How to protect a carbon bike frame?
With the maturity of carbon brazing technology, carbon brazing bicycles are becoming more and more common. Carbon brazing bicycles have become mainstream in the market and become one of the choices of countless cycling enthusiasts. However, carbon brazing is still a little expensive and expensive. The most expensive carbon-braced bicycles are tens of thousands of dollars, but the cheapest carbon-braced bicycles cost thousands of dollars. As a new generation of bicycles to replace the old-fashioned bicycles, carbon brazing has amazing advantages, such as light weight and high hardness. The shock absorption effect is good and the plasticity is strong, but people usually buy high-priced items not only for the function of the product, but also for its service life. However, for a high-value item, you just overuse it without maintenance, then it The service life of the bicycle will definitely be reduced, so if you want your carbon brazing bicycle to be more durable, you must know how to properly maintain it. Below I introduce some ways to maintain the carbon brazing bicycle
1. It is forbidden to slam the carbon brazing frame with sharp objects
Although the carbon fiber material has very high mechanical properties, the impact of sharp objects may destroy the carbon fiber structure
2. Avoid Excessive Squeeze
Excessive extrusion may also cause damage to the carbon brazing frame. There are recommended torque values for bicycle parts in our bicycle manual. Please use the recommended torque values to fasten the parts. At the same time, please do not turn or pull the carbon fiber seat tube and handlebar in the tightened state. If you need to adjust the position or angle, please loosen the parts first and then operate.
Special attention should be paid to the fact that carbon fiber bicycles should not be clamped to the main body of the frame when they are repaired or loaded with parking racks; during maintenance and assembly, attention should be paid to the clamping position, and the frame should not be clamped.
3. To use a special carbon brazing anti-slip agent
The relatively low torque required for carbon fiber frames and parts also has the disadvantage of being prone to slippage. When you install or adjust the carbon fiber seat tube and handlebar, you must not try to tighten it vigorously. You need to evenly apply the carbon fiber anti-slip agent to the parts that need to be tightened to increase the friction between the contact surfaces to prevent slipping, and then Tighten with proper torque
Scope of application of anti-slip agent: carbon fiber seat tube, handlebar, full carbon fiber seat cushion bow and carbon fiber front fork seat tube force locking part.
4. Avoid high temperature exposure
Although carbon fiber has high temperature resistance, long-term sunlight exposure may cause damage to the exterior paint
There are many reasons for the aging of carbon brazing, including temperature, humidity, wind, air, wear and so on. For carbon fiber boards, prolonged exposure to the sun and increased temperature will indeed lead to aging. The key point is the resin matrix. Commonly used resin matrixes include epoxy resin, bismaleamide resin, etc., and their melting points are different. high, no more than 200°C. In the sun exposure environment, the resin will soften. This is the reason for the aging and performance degradation of carbon fiber boards under prolonged exposure to sunlight.
5. Clean your bike regularly
Routine frame cleaning is also an opportunity to inspect the bike, and the frame should be checked for damage or scratches along with it. Do not use non-professional chemical solvents to clean the frame, it is recommended to use professional bicycle cleaners.
Warning: Do not use strong acid, strong alkali (detergent, sweat, salt) and other chemical-containing cleaning agents to clean the carbon fiber bike to avoid damage to the frame paint.
6. Avoid multiple cuts
If you need to cut carbon fiber parts, such as handlebars and the entire seatpost, be sure to measure carefully and wrap with tape to mark where to cut. Cutting requires a special carbon saw blade, which prevents tearing and fraying of the fibers. Never mark the seatpost where you need to cut it with a pen or a sharpie, as even the slightest scratches can damage the carbon fiber. Instead, you can mark the cut location by wrapping it with insulating tape.
7. Avoid the chain getting caught and stuck
A lot of people have experienced chain drops, especially when shifting gears incorrectly. The worst case scenario is when the chain is dropped and the chain gets stuck between the smallest chainring and the chainstays and gets stuck instantly. Big damage for a carbon fiber bike. When this happens, stop pedaling immediately and avoid further exertion. When you get home, thoroughly clean and re-lubricate your drivetrain. Check your chain for wear, elasticity, etc. Best to replace if necessary.
8. Replace the brake pads
If you alternate between alloy training wheels and carbon racing wheels, it is essential to replace your brake pads accordingly. Although there are dual-purpose brake pads, metal debris left on the surface of the pads can easily scratch and destroy carbon fiber rims.
The above is the basic maintenance of carbon brazing bicycles. If the carbon brazing bicycles are properly maintained, there may be no problems in five or even ten years under normal circumstances. Finally, I hope that every cycling enthusiast can make good use of their carbon brazing. Wei bicycles can achieve good results in cycling
