Surly Disc Trucker – The Ultimate Drop-Bar Touring Bike

The Disc Trucker takes the legendary ride quality of the Long Haul Trucker and adds disc brakes, thru-axles, and modern touring-ready features. Built for loaded touring, commuting, or multi-surface adventures, it excels when rim brakes just won’t cut it—whether due to terrain, weather, or heavy cargo.
