Made for Gravel. Discover Rinos Sandman 6
Sandman 6
Shimano GRX600. The Difference You'll Actually Feel.
The GRX600 gives you 22 speeds through an 11-speed cassette instead of the GRX400's 10-speed setup.
That extra cog means smaller jumps between gears—you're not stuck between "too easy" and "too hard" nearly as often.
The RD-RX810 rear derailleur has a clutch that keeps the chain tensioned over rough ground, which stops that annoying slapping sound and means you won't drop your chain on rocky descents.
The 11-speed chain runs quieter and lasts longer because it's built to tighter tolerances. Shifts happen cleanly even when you're pedaling hard uphill.
After a few long rides, you'll notice the difference—less hand fatigue from shifting, fewer adjustments needed, more time just riding.
Sandman 6
Find Your Rhythm. Keep It.
The 30-tooth small ring up front makes steep climbs manageable even when you're carrying gear. Pair it with the big 34-tooth cog in back and you've got an easy gear for when things point upward. But you're not sacrificing speed—the 46-tooth big ring gives you plenty of top end for fast gravel sections. Twenty gears total that actually work for real-world gravel riding, proven reliable on everything from mountain passes to flat prairie roads.
Sandman 4
Most riders buy an entry-level gravel bike, ride it hard for six months, then immediately start shopping for upgrades.
The Sandman 6 gives you the groupset and components that experienced riders eventually upgrade to anyway—the GRX600 drivetrain with 22 speeds, the 11-speed precision shifting, the hydraulic brakes that work reliably under load.
Same TORAY T800 carbon frame and fork as the Sandman 4. Same 9.8kg weight.
The difference is in the parts that matter when you're far from home: smoother shifts, wider gear range, better modulation on the brakes.
Bikepacking with the Sandman 6
Twenty-six mounting points across the frame give you tons of options for attaching bags, racks, extra water bottles, and whatever gear your adventure requires.
The wide 40mm tires come with reinforced sidewalls to protect against punctures on rough terrain.
Hydraulic brakes give you confident stopping power even when the bike is fully loaded.
Proven reliable in rain, mud, dust, and everything in between.
Wheels You Can Trust.
Every Rinos is precision-trued with TRUDI by Berd, the world’s most advanced wheel truing system.
That means straighter wheels, tighter tolerances, and absolute stability — so you ride faster, corner harder, and never lose performance to wobble or flex.
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.
