Wheels Manufacturing BB30 Shimano & 24mm Cranks
This deceptively simple shim is the answer to a conundrum more and more riders are facing every day - your new frame has a BB30 bottom bracket but you've got a perfectly good set of non-BB30 Shimano cranks. This adapter allows you to run Shimano Hollowtech II cranks (the current two-piece style with external bottom bracket) in a BB30 frame.
