This is the very reason I want a Lemond bike, not to mention steel! I have a Trek 2000 that I have put a seat post on with no setback to move my knees into a comfortable posistion. In turn I have a longer than usual stem to get me streched out like I want, all the while on a frame that I can just barly clear on a level road when I step off!
I only wish I had known the difference before buying the Trek because I would be riding a Lemond now!
