Which bottom bracket do I need? Our bottom brackets are made for US/American shells; Euro shells can work with adapters. Your shell width sets the spindle size you need.

Spindle sizing: spindle length is determined by BB shell width and rear wheel size — 4″+ rear wheels require an XL spindle. Send measurements or photos and we’ll recommend a size.
