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

✓ Universal Compatibility Works with BSA, T47, BB30, PF30, BB86/92, and more
