Cheers guys, it stalled a bit there, I have a 9 speed thumbie and 9 speed cassette but as I went to fit it found I had only a 7 speed freehub :roll: Anyway its prompted to me to build a new pair of wheels. Stans 355's with Hope Ti hubs probably on rev's. Should shed almost another pound though I did quibble about the retro/modern mix.
