10 speed Shimano hub, cassette, mech and STI shifters. Work perfectly when the bike is upside-down. Even pushing the brake lever right over, it's impossible to get the rear mech to touch the spokes.
Ride it up any hill in the 28T sprocket, and the mech pings off the spokes. Always has done. It's not the wheel - I sold the rather underbuilt DT set and built some very tight 32-spoke conventional wheels. Something is flexing under the torque of riding, I think. I'm not talking about bar-snapping levels of effort here either, just any kind of incline. AFAIK the frame (Boardman Team Carbon) isn't cracked, the QR is tight and the bearing cones are properly adjusted.
