Description
Shimano’s 12-speed GRX Di2 features a wireless, gravel-specific cockpit where raised hoods with a ribbed surface texture and anti-slip brake levers provide ultimate hand security, no matter how challenging the ride gets. This secure hand position is enhanced, as it was with the original GRX RX815 Di2 Dual Control Levers, by the placement of the third Di2 button on the inside of the hood.
Whether used as another shift location or for scrolling through screens on a cycle computer, this third button is another way to fully experience Shimano’s electronic Di2 system.
The new dual control levers also employ a gravel-optimised body shape cross-section for seamless integration with flared handlebars. Rounder in shape, the transition from handlebar to hood is smoother, creating a larger surface area to help eliminate pressure points.
