It represents the ultimate expression of gravel performance and is designed to take you anywhere you can imagine at full speed. The S-Works 12R frame weighs just 725g, incorporating revolutionary breakthroughs from the Aethos to create a gravel bike that climbs efficiently, floats over challenging terrain, and weighs less than a full water bottle. The 10R frame option weighs 825g for those seeking an alternative. With 47c/650b x 2.1 tire clearance, the Crux offers Diverge-level capability, allowing you to tackle diverse terrain with confidence. The frame features Rider First Engineered design, a threaded bottom bracket, 12x142mm thru-axle, flat-mount disc brakes, and an UDH dropout. The geometry is nimble, supple, and reactive, delivering responsive pedaling and a supple ride. The design is inspired by Crux's iconic history in cyclocross, with race-influenced fit and performance gravel geometry that makes it equally at home on gravel or pavement.
