Description

The BIKONE BB86-92 OVERSIZED Steel Bottom Bracket 29mm Spindle is a solution specially designed for frames whose press-fit cup has widened through use. Compatible with SRAM DUB (29mm spindle) cranks, it restores a perfect fit to the bottom bracket, without play or creaking.

Its slightly oversized cups (approximately 0.05mm larger than the standard version) compensate for the widened housing to restore a secure fit.

It retains Dual Cup Technology (DC Tech) and high-quality chrome steel bearings (ABEC5/P5), for smooth, long-lasting rotation.

Its high-strength aluminium cups ensure excellent mechanical durability over time.

Note: for SRAM DUB Wide cranks, a DUB Wide adapter kit is required. An effective solution for extending the life of a worn frame.
