Key highlights
Crux's FACT 10r Carbon frame builds on the breakthroughs that made Aethos the lightest bike ever, with frames across the Crux range as light as 825 grams.
wide-range 10-46t gearing with wireless electronic shifting brings flagship AXS performance to an accessible build.
25mm internal width, 32mm-deep carbon rims on DT 370 hubs, paired with 700x40mm tubeless-ready Pathfinder tyres for speed and grip on loose surfaces.
up to 47c on 700c wheels (or 650b x 2. 1″) gives Diverge-level capability for tackling rougher terrain than a typical race gravel bike.
