Coming from road frame geometry to a somewhat slack tiathlon geometry has been incredible. (75deg v. 78deg.) My MPH average has gone up about 4mph. Previous ride was aluminum with a very stiff rear triangle. The Spectre accelerates just as well, climbs even better (less weight), descends well in a straight line, and corners somewhat loose. But racing a triathlon it's alot of straight racing anyways. This bikes rocks. I rode Cervelo, and QR and this bikes beats the pants off them. A little more money but a heck of a better deal. Finish is great. Welds a very clean. Beautiful bike!!! Great tri bike. (I am 5'9" 175lbs.)
