Wow the Stache's original geometry really is a snapshot of another time. Incredible that it was just 5 years ago. How much things have changed. It's an interesting reminder that not every bike has to be crazily progressive, that there is room for a range of options. Trek's new bikes are hardly pushing the limit of what's possible and that's great.
456mm of reach in XL with 420mm chainstays and a 73' STA sound pretty extreme to me now!
