OSBB Ceramic Bottom Brackets

Since 2004, VCRC Ceramic Bottom Brackets have been providing extra speed and durability to bicycles around the world. For Cycling, Triathlon & Mountain Bike!

In this category you will find our VCRC Ceramic OSBB Bottom Brackets.  

Specialized has two versions of OSBB, based on their measurements at the BB shell.  First is their 42mmx68mm, essentially BB30.  The second is 61/68mmx46mm, essentially PF30.  We have both below.  You will need to measure your frame's BB shell in both width and inner diameter to determine which version you have.
