Product Description

F1 Ceramic bottom brackets are designed and built to be serviceable, durable and silent. The quality starts with our bearings. Made in the USA, 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. 

So you have a Specialized OSBB frame but use a Shimano 10/11 crank? What do you do? Our new BB uses cups that thread together inside your OSBB frame using two regular Shimano BB wrenches and comes with our ceramic bearings already pressed into the cups. So now your OSBB frame has our Shimano 10/11 BB pressed in with no need for adapters! Please note, this is for OSBB frames that have a 68mmx42mm ID BB shell.  We also have one for OSBB 61/68mmx46mm.

This new threaded version works great with OSBB frames that might be slightly out of tolerance since the cups thread together internally which holds them tight. It is also great with with good tolerance frames as the cups will be secured via the threads and not walk out or move around.
