Stevens was showing off their new bike at Eurobike's Demo Day, but there was no test riding this bad boy.

Cycling tradeshows always provide a showcase for extreme envelope pushing and Stevens is doing just that with its new-for-2014 Comet SL. The German bike-maker's flagship road machine will be available in a variety of configurations, including this ridiculously light, 10.8-pound 58cm build that retails for 12,990 euros (or about $17,400 at current exchange rates).

Highlights of this über climbing machine include a pair of special edition Lightweight Meilenstein Obermayer tubular wheels with 50mm rim sections and a claimed weight of 900 grams. German carbon component maker THM provides the Nimbus fork (283 grams), Fibula brakes and Clavicula cranks (all carbon), and the cockpit is by AX Lightness (again, all carbon). In fact the only thing that's not ultra-weight weenie is the Shimano Dura Ace Di2 drivetrain.

Claimed weight on these 50mm hoops, just 900 grams.

"For the rest of the group, instead of going super light we went reliable," explained Stevens marketing manager Volker Dohrmann. "It could have been lighter if we went with SRAM Red or Campagnolo Super Record."

Tufo Elite Jet tubular tires, and AX Lightness saddle and seatpost complete the build. Available sizes range from 50cm to 62cm, and it also comes in red.

If you don't have a year's worth of college tuition to dump into a road bike, the Comet SL (claimed frame weight 795 grams, size 56cm) can also be spec'd with a variety of more traditional options from Shimano, SRAM and Campagnolo.
