Purchase in order to remodel my brother's cross bike. The BB (square taper) was tightened tightly, and at the 300 mm monkey the teeth did not stand at all. Kusuken was a 600 mm KOKEN spinner, and when I put my weight gradually, I got a dull touch and the BB started to turn and I could safely remove it. If so, you can easily remove the BB of Campagnolo painted with Loctite and maintenance seems to be progressing. The price is steadily high compared to other single tool, but I think that it will do more than that.
