Nice tool

Well built. Socket fitment is a nice option to have. Fits well.

Direct Mount Rings

Get this if you use Raceface direct mount rings, no issues.

Get this for Cinch direct mount rings

I've used it several times

I haven't touched as ISIS bottom bracket in years, but this tool is what you need to change the direct mount ring on a RaceFace Cinch crank. The 32C variant is best used with a large crescent wrench or a vice. The 22C option has a 3/8 socket fitment.

Change Chain Rings

I bought this to be able to easily swap out chain rings and it works great!

A New Use for an Old Tool

I've put it through the wringer

There were only a few times I had ever used a Shimano/ISIS BB tool in my bike mechanic days and that was just to remove old, stubborn bottom brackets. Now though, it's got a new job. Instead of creating a new, proprietary tool for the installation and removal of Direct-Mount chainrings on Cinch interface cranks, RaceFace simply cut the direct-mount lock-rings to work with the BBT-22C tool. I'm happy to see a dusty tool get a new use.


Will this remove the Shimano cassette as...

Will this remove the Shimano cassette as well as the bottom bracket?

I know this is an old question, but for other people looking: This will remove just the bottom bracket, you need FR-5/FR-5G or similar to remove the cassette
