The Opus Horizon is a 700c aluminum-framed gravel bike, that will take you on and off any road in BC or Canada.
Available in store
CloseThe 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, takes 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.
