Specifications

Material: Steel 45, offering a strong and durable foundation for high-performance applications.

Diameter: Φ10 mm, ensuring compatibility with standard bicycle components.

Length: 242 mm, optimized for effective operation in suspension setups.

Roughness: Ra < 0.2 μm, providing a smooth surface that minimizes friction and wear.

Hardness: HRC 40-45, ensuring resistance to deformation and wear under stress.

Benefits

The QPQ (Quench-Polish-Quench) surface treatment significantly enhances the hard chrome shaft's durability and corrosion resistance, making it ideal for various environmental conditions. This treatment also improves surface hardness, leading to better performance in absorbing shocks and providing a smoother ride.

Applications

Ideal for high-performance bicycles, this hard chrome shaft contributes to improved handling, control, and overall riding comfort, making it a crucial component for both recreational and competitive cyclists.

How to repair the bicycle shock absorber if it can't be pressed down?

1. Check and clean the spring and piston inside the shock absorber. Dust, mud, or other impurities may have stuck the spring or piston, causing it to not work properly. Use a clean cloth or paper to clean the inside.

2. Reinstall the spring. Make sure the spring is properly installed in the shock absorber and is not twisted or damaged. A new spring can be replaced if necessary.

3. Check whether the hard chrome shaft is worn or damaged. If the piston rod is worn or damaged, a new piston rod needs to be replaced. When installing the new piston rod, make sure it is aligned with the hole in the shock absorber.

4. Check whether the sealing ring of the shock absorber is damaged or aged. If there is a problem with the sealing ring, a new sealing ring needs to be replaced to ensure that the fluid inside the shock absorber does not leak.

5. If the above steps do not solve the problem, you may need to replace the entire shock absorber. When buying a new shock absorber, make sure you choose the right one for your bike model.
