i dont know an aweful lot about them but the road wheels are supposed to be the mutts nuts and they are made by HED so im pretty sure they are up to the task.
the guy who sold them to me bought them in september and has barely used them, apart from a few quick spins round the block!
I've read good reviews of these. Specifically the Powertap ones..
