Sterrato 9.9 incorporates the 1×11 GRX 810 drivetrain from Shimano.
SHIMANO GRX, with its gravel specific ergonomics, optimized gearing options, rugged reliability, and quiet and stable drivetrain, sets itself apart from the rest of the component world. It isn’t a reworked set of road components. It represents a ground up look at how cyclists want to explore their world. SHIMANO GRX helps you eliminate excuses, instead urging you to try that rough sidetrack or ride that little bit longer. It offers you the option to Explore Beyond.
The model includes Shimano GRX RX810 hydraulic disc brakes as well as an adjustable KS LEV Si seat post. The tires of the Sterrato 9.9 are WTB STp i23, tubless ready, which means that the bike can be ridden without inner tubes, as well as at lower pressure. This in turn improves traction and increases riding comfort. Sterrato behaves very well on both steep ascents and descents, and once you step on a forest path, you will be pleasantly surprised.
