Great quality from Unior, intended for professional use or for the home workshop where the quality must be top-notch.

Can be used for the vast majority of external bearings, such as Hollowtech II, FSA, Giga X Pipe, and many others.

Also included is a small trigger for Shimano cranksets, this attaches to the large trigger with a magnet and can also be used with a spanner.

Also fits Shimano Oversize Centerlock with external spokes.

Does not fit Shimano's Hollowtech adapter for 6800 crank bearings, but it fits regular hollowtech bearings.
