Very reliable tools

- Bavo 15 March 2025

A good quality product as always from Parktool. Can be used to loosen/tighten BBs as well as for disc brakes with an external centre lock. The Shimano crank tool hanging from the tool is a handy extra, although I already had it separately among my tools.

Nice little tool, with water pump pliers it wouldn't work, with this in a jiffy

- Edwin 24 December 2020

Works fine, no damage to the old crank bearings and the new ones back on! Edges are a bit sharp from punching out the plate, but the handle fixes that.
