A necessary evil.
- Familiarity: I've used it several times
RaceFace uses a different spline interface than your standard Shimano or GXP external BB. I believe its to accomodate for the larger spindles the cranks run, but I'm not quite sure. Either way, this tool is needed for install. Has a place to insert a 3/4" torque wrench, and works just fine. Wrap some old bar tape around the handle and you've got a padded grip!
