Upgraded Brake Cable Lengths: The brake cable lengths are upgraded to provide better compatibility.Rear brake cable measures 78.7 inches (200 cm), and the front brake cable is 31.5 inches (80 cm) long.For the brake pipe cables, the rear measures 61 inches (155 cm), and the front is 25.6 inches (65 cm) long.Extending the cable length accommodates a wider range of vehicle models.This can be easily achieved by trimming the cable to match specific usage needs, eliminating the issue of cables being too short for practical applications.

Professional Cycling Brake System‌: Crafted from aerospace-grade aluminum and composite rubber, this brake system maintains structural integrity in extreme temperatures ranging from -30℃ to 80℃.The oxidation-resistant coating significantly extends durability, while the metal-plastic hybrid core design ensures anti-deformation performance.Paired with high-density PU sheathed brake cables, it delivers 300% enhanced wear resistance, guaranteeing precise braking for over 10,000 cycles.Rigorously tested with 200N lateral force, the system provides all-weather reliability for safe rides.

Installation Guide: To install the brakes onto the bike, start by aligning the holes on the brake components with the corresponding holes on the bike's frame.Next, thread the brake cables through the brake wire tubes and secure the position of the tubes.Then, fasten the brake line to the bolt and fit the brake caps in place.Adjust the length, distance, and position of the brake tube as needed, ensuring the brake line is securely fixed.

Compatibility: This brake kit is suitable for most mountain bikes and road bikes equipped with brakes. The brake arm tension is adjustable, ensuring the frame/forks are in the correct position. It's easy to adjust the spring tension within the internal brake bow. If you encounter any issues with this bike brake kit, please reach out to customer service promptly for a satisfactory resolution.
