I've had mine just over two weeks now... So far, so good... Definitely a fast, responsive ride. The geometry takes a little getting used to -- especially the seat tube position ahead of the bottom bracket. But, I think I have about got the saddle dialed in, finally.
Speaking of saddles... What the heck is Trek thinking putting an ultra-padded "lux" saddle on a hard core racing bike!?!?! Swapped that thing out right away!
