Description
Ok...so you have BB30, PF30 (Please See Notes in Spec) or a Specialized OSBB frame, but you need to run a Shimano crank? No worries.
Our Praxis Works Conversion Bottom Bracket is just what you're looking for. Made to fit in either BB30 or PF30 frame, the conversion BB is designed to be rock solid for a Shimano Hollowtech II crank to be installed in your frame.
68mm for Shimano Road Cranks.
73mm for Shimano MTB Cranks. “How do I know the conversion bottom bracket drive cup on the BB30 and PF30 is installed completely?”
ANSWER/INSTALL TIP
As you’re threading down the Drive cup and the collet system starts to expand, grab a 2nd BB tool to hold the Non-Drive Cup steady.
This gets you more leverage when threading down the Drive Cup and also gives you a tactile feel of when the Drive Cup has fully bottomed out on it’s machined ‘stop’. This ‘stop’ sets the Drive Cup bearing precisely on Shimano spec, and also sets the collet expansion.
Please Note: The machined stop prevents the collet from over expanding past exact spec. Designed for Shimano™ 24mm Hollowtech II cranks.
