The Disc Trucker is Surly’s disc touring bike and this year, the brand revamped it a bit, adding a bunch of crucial details:

Updates:
-Dynamo routing on the fork, plus three-pack mounts on the blade and every braze-on you’ll ever need for racks, fenders, water bottle cages, and more
-12mm thru-axles for a stiffer feel and increased stability when fully loaded
-Shortened seat tube and slightly sloped top tube for improved stand-over clearance, plus increased stack height for a more upright and comfortable riding position on those long hauls
-Spec’d with the Truck Stop Bar and tubeless ExtraTerrestrial tires for dependable handling and traction
-Flat-mount disc brakes
-Frame sizes 42–56cm are available with 26” diameter wheels, while frame sizes 56–64cm are available with 700c diameter wheels
-Clearance for 26” x 2.1” tires with or without fenders, or 700c x 47mm with or without fenders
