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, travelling light or fully loaded, one bike does it all. The Horizon AL 105/GRX.
