Soo... anyone know what tool to use to remove this type of bottom bracket?



I looked all over and couldn't find a thing...

Thanks in advance!

Park Tool BBT-22 or any other bike-tool maker's equivalent. Good tool to have, there's a lot of those BBs out there nowdays.

Here's where I'm confused:
"The BBT-22 is a shop quality tool for installing and removing Shimano® and ISIS Drive® splined 20-tooth bottom bracket cups."

My bb cups have 16 teeth (4 sets of 4 teeth with gaps in-between).

That tool will still work, it's pretty much a de facto industry standard at this point.

Ok, thanks

btw, what's the difference between the bbt-22 and the bbt-22c?

It's another Shimano induced standard. the UN type cartridge BB assembly ..

Will either one work?

Nevermind, found my answer on Park Tool's website. The only difference is the particular composite of metal used to manufacture the tool.

In Park Tool's nomenclature, the C designates it's on a retail display card that can be hung from display hooks.
