Carbon Performance, Ready for Any Terrain
The RINOS Sandman 4.0 is a premium gravel bike designed to handle everything from fast road rides to unpredictable off-road trails. With a lightweight TORAY T800 carbon frame and fork, it strikes the perfect balance between strength and agility, offering responsive performance and long-distance comfort.
Designed to Fit Every Rider
Available in five sizes (50–58 cm) and weighing only 9.8 kg, the Sandman 4.0 fits riders from 155 cm to 195+ cm. A carbon seat post and ergonomic ROCKBROS saddle round out a ride built for all-day comfort.
Precision in Every Shift
Equipped with the Shimano GRX 400 2x10-speed groupset, including the RD-RX400 rear derailleur and 11–34T cassette, this bike offers crisp, responsive shifting in every condition — from steep climbs to fast descents.
Confidence on All Surfaces
The bike rolls on lightweight RINOS rims with NOVATEC hubs, delivering sharp acceleration and smooth handling. Paired with CST 700x40C tires with sidewall protection, the Sandman 4.0 grips confidently whether you’re on gravel, asphalt, or forest paths.
Hydraulic Braking, Instant Control
The full Shimano GRX400 hydraulic disc brake system ensures powerful, predictable stopping power — giving you the confidence to ride harder and descend faster.
