F1 Ceramic bottom brackets are designed and built to be serviceable, durable and silent. The quality starts with our bearings. Made in the USA since 2003, using premium components, and built to order. Each part of the bearing is individually graded before building your bearing. This combination of quality, strength and reliability gives us the confidence to offer you a 7 year warranty.
This kit is for the BB90 press in bearing system and Shimano 10/11 speed cranks. The BB90 system is found on 2008 and newer high end Trek Madone, Trek Domane and Gary Fisher bikes. Lower model Madone and Domane frames use BB86 (see our BB86 kit) so be sure to check what type of frame you have for compatibility.
