VAR (30) and Campagnolo (793/A) offer similar tools. The VAR offers several jaws to fit a number of different fixed cup designs. The Campagnolo only fits Campagnolo and its copies (36mm flats), of which there are many. Neither is cheap, but they work. Every time. Without damaging either the cup or the frame.
