Overview
About this bike
YOU DECIDE WHERE IT TAKES YOU The Horizon AL 105/GRX takes our proven Horizon geometry to new extremes. A dropped chainstay gives you clearance for 45mm tires and the ability to mount 650B wheels with up to 50mm tires. All that, plus a threaded bottom bracket, take you places you never thought possible. Meanwhile, the rugged alloy frame shoulders heavier loads on multiple mounting points, including on new top tube mounts. On road or no road, traveling light or fully loaded, one bike does it all: the Horizon AL 105/GRX. - Proven Horizon Progressive Geometry to master all surfaces - Full carbon fork with triple mounts for bottle or bags - 11-speed Shimano with GRX rear derailleur - Big clearance for 700 x 45 tires, can be used with 650B x 50 wheels and tires - Rear rack and fender mounts, 5 bottle and top tube mounts
