Xenith Enduras use the same top-level manufacturing techniques and materials as our award-winning Xenith Competition series. But Enduras roll on slightly stretched wheelbases, with marginally less aggressive cornering geometry, for more stability and a little extra ride comfort. And the head tubes are slightly longer, for less drop to the handlebar and a more upright posture that trades away just a little bit of aerodynamic slickness (which is still there for you in the drops) for a big payoff in reduced neck and back strain for those long-mileage days.

Superlight wheels—which any racer will tell you are the most critical speed component—and the combination of compact cranks (with a triple ring option available on the Comp) plus 11-28 or 30 tooth cogs gives you a big boost on climbs, with plenty of go-power to whoop it up on descents, where you’ll make the most of the Endura’s incredible handling manners and really appreciate the superb road feel of that full carbon hollow-crown fork.
