The Shimano 12-speed Shimano GRX Di2 Dual Control Lever delivers fast, wireless shifting for gravel and mixed-terrain riding

New dual-control levers employ a gravel-optimized body shape cross-section for seamless integration with flared handlebars
Rounder in shape, smoother handlebar-to-hood transfer, and larger surface area helps eliminate pressure points
Front of the bike wireless gravel-specific cockpit. Two easy-to-change CR1632 batteries are long-lasting with a 3-4 year life
Smaller diameter wires connect directly the battery to each derailleur, eliminating the need for junctions, and streamlining the build process
Central internal battery simplifies charging and remains secure over the roughest roads, trails, or whatever less travel path you choose
Ability to assign the brand new FRONT SHIFT NEXT function to any of the three shift buttons
