The Xenith Endura 3 uses the same manufacturing techniques and materials as Jamis’s Xenith competition series frames. The frame is constructed with high modulus carbon fiber, Dyad Ultra lay-up, tri-oval shaped top and down tubes, tapered 1 1/8-1 1/2-inch head tube, BB30 bottom bracket shell, asymmetrical chainstays, and a forged one-piece dropouts with replaceable derailleur hanger. What separates the Endura 3, and the rest of the Endura line, is that it rolls on a slightly longer wheelbase, with less aggressive geometry. This provides more stability and extra ride comfort. Along with the stretched wheelbase, the head tube is taller, for less of a drop to the handlebar and a more upright riding position. The Endura 3 is outfitted with Shimano Ultegra shifters and deraileurs, an FSA SL-K compact crankset, American Classic Victory 30 wheelset and a full Ritchey cockpit rounded out with a Selle San Marco Ponza Power Arrowhead saddle. The Endura 3 retails for $3100. For more information on the Endura 3 and the entire the Jamis line of bikes visit www.jamisbikes.com.
