Lets get a list together of what goes with what. 128mm fits pre 08 Scalpels with 3x9. 122mm fits pre 08 Scalpels with 2x9. 132mm fits the carbon Rush with 3x9. I am curious what length the new Scalpel 2x9 comes with. I also have a 131mm and have no idea what that was made for. I heard that the new Scalpel will use a 128mm with it's 2x9 spider. I have a Taurine that came with a 132mm and 3x9. I'm wondering if I use the 2x9 spider with a 128mm on the Taurine if it will work. Road bike info needed also.
