Material seems to be too soft for use

  • Familiarity: I've used it once or twice and have initial impressions

First off, why are there so many specific and proprietary bike parts? Why does one BB need to have a unique number of notches to differentiate it from another one?

Aside from that, I only used this tool once to swap a BB from one bike to another. After one use, the part's metal had bent and was completely stuck on the 3/8

slips off super easily

  • Familiarity: I've used it several times

Not sure if it is the fault of raceface's BB design, or this tool, but man this thing is a pain to use. As soon as you apply torque the tool starts slipping off the bottom bracket. Very hard to use with your bike in a stand or upside down. Best way is to lie bike on its side so you can get downward force so the tool doesn't slip off. Gets the job done, but very poor design.

Have you tried this inn comparison to Race Faces BB30 Tool? If so - which is better option?
