The GRX Di2 ST-RX715 Shift/Hydraulic Disc Brake Lever Kit delivers fast 1x12 speed wireless shifting and powerful, easily controlled braking for any mixed terrain exploration. Up front, the easily programable wireless Di2 levers have a shape and lever path that is optimised for great ergonomics on handlebars with a flared drop, ensuring easy shifts and great bike control from either the hoods or from the drops of the handlebars. The brake lever has 16.4mm of adjustment so it can be positioned exactly where they can be operated comfortably, and that mineral oil filled hydraulic lever is linked up to powerful and easy to modulate BR-RX410 flat mount calipers which, thanks to increased pad to rotor clearance, are much quieter than their predecessors. Add in exceptional battery life, comfortable rubber hoods, and an attractive price, and this lever kit makes the upgrade to fast and precise electronic shifting and powerful hydraulic disc brakes an easy decision.
