Shimano TL-FC32 Werkzeug für Hollowtech II Lagerschalen

It's fine if you don't mind damaging the cups. First of all, it's quite tricky to keep it in position so that it doesn't slip of the BB cup. Even if I managed this, it always bit into them quite deeply, leaving not nice marks. I also wonder how long would cups last if you used it regularly (e.g. if you replace only bearings instead of whole cups).

Something like "Birzman Hollowtech II B.B. Tool" works much better - the contact area is whole circle and it is also deeper.

excellent tool to remove centerlock nuts for 15mm axles.

great home mechanic tool to mount your BB cups and centerlock nuts for 15mm hubs
