YST EXT THREADLESS BOTTOM BRACKET

Got stripped threads on your 68mm English BB shell? The YST EXT Threadless Bottom Bracket is your fix. This clever threadless design threads to itself, eliminating the need for a perfectly intact frame—just a snug, bevelled cup fit. Lightweight alloy body with sealed bearings keeps things smooth and protected. Works with both Shimano-style straight 24mm axles and SRAM-style stepped 24/22mm axles (spacer included). Install using standard hollow-tech II BB tools on the 44mm cups with 16 external notches. Problem solved, ride on.
