THE tool for Shimano rotor lockrings.
- Familiarity:
- I've put it through the wringer
When you're running through-axles you often have to take the end caps off to properly torque your rotor lockrings, this is the tool that lets you torque 'em down properly and still get the end cap back on.

Good enough for the job
- Familiarity:
- I've used it several times
A bottom bracket gets installed once, and serviced once or twice a year. The Park Tool BBT-79 works well. Fits well on the parts and has a 3/8" drive for a torque wrench.

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.
