Specification AutomotiveFitType : vehicle_specific_fit AutoPartPosition1 : front AutoPartPosition2 : rear Brand : Hayes BulletPoint : Hayes L6 Disc Rotor 160mm with Hardware BulletPoint1 : Floating structure prevents brake track from expanding and excessive deformation caused by brake temperature rises The slight movement of the disc optimizes contact with the pad and reduces pad and disc overheating. Improves braking efficiency Aluminum spider improves heat dissipation BulletPoint2 : After FEM analysis, it was verified by rigorous lab and road tests and the driving testing was performed with professional riders for over one year under all weather conditions. In the most extreme tests, the rotor has passed a long braking test before it reaches 500 degrees Celsius without deformation. Five floating rivets on the rotor allow the rotor to expand and help dissipate heat and prevent outer disc deformation BulletPoint3 : The disc rotors utilize FEM analysis to ensure maximum braking performance while minimizing weight. 2-piece outer disc and spider construction with a floating structure with a little bit of play in the axis BulletPoint4 : Size: 5.5 inches (140 mm), 6.3 inches (160 mm), Weight: 4.3 oz (110 g), 5.2 oz (130 g), 6.3 inches (160 mm), Material: Japan SUS-410 (Outer Disc), 7075 Aluminum (Spider) Thickness: 0.06 inches (1.6 mm), Compatible with: Shimano Center Lock Recommended Use: Load, Gravel Recommended Pad: Resin BulletPoint5 : NEW DESIGN: The disk brakes for the bike are designed accurately, are sturdy, and adopt the arc sector hollow design.
