Jamis Xenith SL Di2

Jamis crossed the boundary of bicycle design and built their Xenith SL Di2 for one thing only: pure speed. Cutting-edge frame materials and features such as a BB30 bottom bracket and oversize fork crown make this futuristic flier's ride quality like no other. Its carbon frame and fork use proprietary fiber layups and varying tube diameters for a finely tuned ride. If that weren't enough, the Xenith delivers unparalleled shifting execution thanks to Shimano's revolutionary electronic Di2 components; you'll never want to go back to cables again. It rolls on a set of Zipp's industry-leading 404 tubular carbon wheels, and more high-tech goodies include Ritchey's carbon bars, stem, and seatpost, silky smooth Vittoria tubulars and a Selle San Marco saddle with carbon rails.
