A little bit about me. I'm 5'8" 172 pounds and about 10% body fat. I'm a good time trialist and really good at sprinting but I have been know to get shelled on some longer hills or really short and steep ones. I want to invest in a tubular wheelset and was wondering which direction to go .... a bit heavier aero rim or a lightweight climber rim. Does the aero rim make that much of a difference for breakawys? I am not afraid to fly off the front and attempt this quite often depending on the course layout. I guess what's eating me is that I see guys off the front the entire race on some stages of the tour and their wheelset is nothing close to deepdish aero's? Help me out folks!
