Since I am used to Shimano (DA9 on one bike and U9 on another) I may not like the thumbshifters but if I do, I am already thinking of swapping out the Veloce group to the Chorus group (fr and rr der, cranks, shifters, cassette, chain) as this frame is worthy of higher end Campy parts. I may go with Mavic brakes and researching for a different set of wheels (tops on list are the Eurus or Neuvations R28 Aero or R28 SL). For stock wheels, the Mix has Veloce hubs laced to Colnago Balance rims and I have no idea how good and durable these will be. Any recs from all of you Campy veterans? Thanks and Ride ON!!
