I had to switch to the Shimano's.. and sold the HED's. I picked up a set of Tubular Duca Ace C-25's.. the full-carbon type (not the one with the aluminum braking surface).. but I decided against going tubular because I just know so little about them and someone tried to teach me, but it just seems like way more hassle.. so now I gotta sell the Dura Ace wheels. lol Once I do, I'll probably pick up a set of the HED Ardennes Black.
