Hey all, building my first Campy bike soon, and I am currently shooting for a full 11 speed Chorus group, but I have heard that 11 speed, while great, requires a lot of extra maintenance to shift perfectly and quietly. So, I thought about it, and a set of Powercordz could help the issue considering they don't stretch at all. Anyone have any experience here? They say they will fit Campy, and if they would, that WOULD keep everything closer to adjusted for longer, correct?
