PF4630 Composite

Our Press-Fit 4630 Composite bottom bracket has been designed to solve two common limitations of this type of BB:

Bearing Protection: In some cases, metal bottom brackets may suffer excessive pressure from the frame, accelerating bearing wear and increasing friction. High-resistance composite is more malleable, absorbing stress and ensuring smooth, long-lasting rotation.

Smart Maintenance: Many cyclists prefer to replace their bottom bracket frequently. Our composite structure offers a lightweight, cost-effective option without sacrificing ROTOR’s precision and quality standards.
