How do you take one of the lightest complete bikes and make it even lighter? Add a Lauf Fork and THM Clavicula cranks, of course.
Following frame tweaks and a production shift to Germany announced earlier this year, the chassis comes in at under 800g for a size Large. Until now, the lightest complete build we’ve seen from them was a 16.2lb bike with Di2 parts. Now, they’ve pushed more than a pound lighter by running XX1 on one of the lightest cranksets and forks on the market.

The tubes are primarily UD carbon for its stiffness, when woven sections placed at junctions and high stress areas to keep it strong. The Lauf leaf spring fork certainly contributed to the bulk of the weight loss while still providing some suspension.
AX Lightness makes up most of the cockpit parts and headset.
Ridges on the seat tube helped improve lateral stiffness at the BB and enabled them to switch to PFBB30 without sacrificing performance.
Thru axle dropouts are molded in woven fibers and are ready for either electronic or mechanical systems. On earlier versions, the cable would pop out of the rounded indent just above the dropout’s cylinder, but they reworked the design to better work with XX1’s rear derailleur cable entry angle.
A Carbon-Ti thru axle bolt forgoes the lever to keep it light and clean. Magura brakes, AX lightness carbon wheels and Schwalbe tires round things out.
Complete weight without pedals is just 6.86kg (15.12lb).
