Specialized Crux Expert Gravel Bike
Its exceptional design combines massive tyre clearance with a performance-oriented gravel geometry, making it not only the epitome of gravel performance but also your exclusive ticket to the realm of gravel enlightenment.
Featuring intuitive and crisp-shifting the SRAM Rival eTap AXS hydraulic disc groupset, ensures seamless and responsive riding experience. The choice of tough Roval Terra C Disc wheels guarantees stability and reliability on any gravel path you choose to conquer. The 2Bliss Ready, 700x38mm Pathfinder Pro tyres add to the bike's versatility, providing superior traction and control over diverse and challenging terrain.
Crux Expert Highlights
- 725g S-Works 12r and 825g 10r frames. We took the revolutionary breakthroughs that made Aethos the lightest bike ever and applied them to the Crux. The result? A gravel bike that climbs like a dream, floats over nightmarish terrain, and weighs less than a full bottle in your cage.
- Nimble, supple, and reactive. Responsive at the pedals, supple in the saddle, the Crux blends speed and comfort for an unrivalled ride feel
- Performance gravel geometry and a race-influenced fit is inspired by Crux’s iconic history in cyclocross
- The combination of clearance to weight unlocks all-new riding potential
- Fast-rolling Roval Terra C 700c wheels deliver rapid acceleration and durable performance
- 38c Specialized Pathfinder Pro tyres boost grip across a range of surface types
- Fully-wireless SRAM Rival eTap AXS drivetrain provides crisp, reliable shifting across the wide 12-speed range
