BOTTOM BRACKET

The Heart of Your Drivetrain

Precision Engineered for Smooth, Silent Performance Every pedal stroke starts here. CRODER bottom brackets are designed with black-oxide ceramic bearings and innovative TUBE-LOCK technology to deliver unmatched smoothness, durability, and compatibility with all major standards.

Why CRODER Bottom Brackets?

Traditional press-fit bottom brackets rely on frame tolerances. Even 0.01mm of variance can cause movement and noise. CRODER's TUBE-LOCK technology solves this.

✓ TUBE-LOCK Design
The two bearing cups connect internally, eliminating independent movement

✓ Black-Oxide Ceramic Bearings
Ultra-smooth G5-grade ceramic balls reduce friction for effortless pedaling

✓ LAYERED CORNER Technology

Reduces friction between the

BB and frame shell where creaking starts

✓ All Specificaton You Can Find from CRODER
The BSA, T47, BB30, PF30, BB86/92, BB Right and more specification, you can find them from CRODER BB series
