Shimano GRX, the new gravel components designed for 11-speed drivetrains and cassettes up to 42 teeth. With the new 48/31-tooth crankset, the GRX components offer a wide gear range for a variety of applications, from gravel and cyclocross to touring. Shimano GRX, the first gravel-specific component family designed equally for fast progress and safe bike handling on loose surfaces, is the result of an intensive and extensive research, testing and development process that incorporated information and feedback from countless riders who are out and about on trails, forest tracks, gravel roads or tarmac. Whether it’s gravel riding in the strictest sense, road bike adventures off-road, bikepacking, commuting or the demands of competitive cyclocross riders: Shimano’s GRX components offer countless options that leave nothing to be desired, from gear ratios and spacing, customisable ergonomics and integrated control of dropper seatposts right through to specific gravel wheelsets with wider rim profiles. Either the 11-speed road or 11-speed MTB cassettes can be used.
Shimano STI ST RX810 Disc Lever:
With the ST-RX810 disc brake lever, Shimano introduces a very compact brake lever for hydraulic disc brakes and mechanical shifting systems. Ergonomics specially adapted for gravel use are characterised by a brake lever pivot point raised by 18 mm, a curved lever shape and non-slip textures on the contact surfaces, ensuring optimum grip even on the roughest terrain. These disc brake levers are based on Ultegra STI technology and are compatible with Shimano’s mechanical Dura-Ace 9000, Ultegra 7000 and 105 7000 11-speed groupsets. Shimano’s engineers have succeeded in integrating a mineral oil cylinder, including a complete braking system, into these nevertheless very compact mechanical shift-brake levers. The brake levers are made from aluminium; this technology guarantees maximum stiffness, durability and a robust design. Thanks to the improved positioning of the brake cable, a smooth braking action is achieved, resulting in optimised control in extreme conditions. The Dual Control shift/brake levers can be optimally adjusted to the rider via a grip width adjustment and are also very well suited for riders with small hands. Shifting can be performed much faster with the new shift levers. This is achieved through a 20 per cent shorter cable. The grip sections feature an ergonomic design for improved comfort – even over long distances. The GRX STI levers can be combined with the BLRX812 auxiliary brake levers. These are mounted between the shift levers and the brake on the top tube, just like classic cross-country brake levers. This ensures full control over the bike in every riding situation.
