The 2026 Specialized Crux Expert with Shimano GRX 825 Di2 1x12 is engineered for riders who demand the ultimate blend of lightweight efficiency, confident handling, and gravel-specific performance. At its heart is the FACT 10r carbon frameset, tipping the scales at just 825g, inspired by the minimalist philosophy that made the Aethos the lightest road bike ever. Rider-First Engineered geometry ensures the same tuned balance of stiffness, compliance, and responsiveness across every size, giving you precise handling whether you’re hammering up steep grades or threading technical descents. The frame’s massive tire clearance and clean cable routing enhance both capability and aesthetics, making the Crux a true race-ready and adventure-capable machine.

The highlight of this build is the all-new Shimano GRX 825 Di2 1x12 drivetrain, delivering lightning-fast, fully wireless electronic shifting with the durability and ergonomics gravel riders need. Paired with a 10-51T cassette, it offers an enormous gear range to tackle anything from high-speed flats to lung-searing climbs. Shimano’s gravel-optimized lever shape and textured hoods provide exceptional comfort and control on rough terrain, while the hydraulic disc brakes offer unmatched stopping power and modulation in all conditions. The simplicity of the 1x system means less to think about mid-ride, freeing you to focus on the course or the adventure ahead.

Rolling efficiency and stability come courtesy of the Roval Terra C wheelset, featuring a 25mm internal width to perfectly support today’s wider gravel tires. The New Specialized Pathfinder TLR 700x40mm tires strike the perfect balance between low rolling resistance and reliable off-road grip, ensuring speed on hardpack and control in loose gravel. The full-carbon fork, wide flared alloy handlebar, and lightweight Specialized stem create a responsive, vibration-damping front end that keeps you planted through rough sectors while preserving steering precision. This setup provides race-day readiness without sacrificing all-day comfort.

Finishing touches complete the Crux Expert’s performance package: a Body Geometry Power Expert saddle supports efficient pedaling and long-ride comfort, while the Roval Terra carbon seatpost with 20mm offset enhances compliance on chattery roads. The frame’s 47c tire clearance (or 650b x 2.1”) future-proofs your build for more aggressive terrain or bikepacking needs, and its featherweight 8.1 kg build (size 56) keeps it agile and responsive from start to finish. Whether you’re chasing podiums at gravel races or exploring beyond the pavement, the 2026 Crux Expert with GRX 825 Di2 delivers a category-defining combination of speed, control, and capability in the lightest gravel platform in the world.
