The Sandman 6 elevates gravel performance with Shimano's GRX600 groupset—a refined 22-speed (2×11) drivetrain that delivers wider gear range and more precise shifting than entry-level systems. The GRX RD-RX810 rear derailleur with its 11-34T cassette provides smooth transitions across technical climbs and fast descents. This is the groupset where Shimano's gravel-specific engineering becomes most apparent, with improved ergonomics and clutch technology that keeps your chain secure on the roughest surfaces.
Built on the same TORAY T800 carbon frame as the Sandman 4, the Sandman 6 maintains the 9.8kg complete weight while upgrading the components that enhance ride quality and longevity. The GRX600 hydraulic disc brakes offer more consistent modulation and require less frequent maintenance than the 400-series. The upgraded Shimano 11-speed chain runs quieter and lasts longer under load. These refinements add up over hundreds of kilometers—less time adjusting your bike, more time riding it.
We've equipped the Sandman 6 with RINOS carbon components throughout—handlebar, seat post, and fork—creating a cohesive system that dampens vibration without sacrificing responsiveness. The aluminum headset provides a reliable interface between these carbon elements. The wider 38mm RINOS rims paired with Novatec 28H hubs create a wheelset that accelerates quickly yet remains stable when loaded with bikepacking gear. Every component choice reflects our focus on building a gravel bike that performs whether you're racing, touring, or simply exploring.
Available in four distinctive colorways and five frame sizes spanning 150 cm to over 200 cm rider heights, the Sandman 6 accommodates a wide range of riders. The bike's geometry balances stability with agility—confident on technical descents, responsive when navigating tight singletrack. Whether you're tackling multi-day bikepacking routes, competing in gravel events, training on mixed terrain, or seeking a capable all-road bike, the Sandman 6 delivers premium performance without the premium price tag. Manufactured in the EU to exacting standards, this bike is built for riders who demand more from their equipment.
