The frame weighs approximately 725g, creating an exceptionally light foundation for a performance-focused gravel build.
Rider First Engineered construction helps maintain consistent handling and ride characteristics across the Crux size range.
47c Tire Clearance & Performance Gravel Geometry
The Crux combines its lightweight construction with generous tire clearance for increased versatility across different surfaces.
The frame accommodates tires up to 47c with 700c wheels or 650b x 2.1", allowing riders to adapt their setup for fast gravel racing, rougher terrain or mixed road and off-road riding.
Its performance gravel geometry is designed to feel responsive and precise while still providing the stability needed for high-speed riding on loose and uneven surfaces.
