Suspension corrected for 100mm travel suspension fork. 100% CroMoly, tapered and butted, striaght-blade

4130 CroMoly steel. Main triangle double-butted. TIG-welded.

Dig the 1x1, a singlespeed mountain bike. It was designed for 26˝ wheels, big tires (clearance for 2.75˝), and single cog and ring drivetrains. Run it with a freewheel, a fixed cog or if you like with an internal gear hub. The 1x1 is made of 4130 CroMoly tubing of our own design, with a custom double-butted main triangle and triple-butted fork blades for a tough yet responsive, lively ride. The geometry is pretty straightforward… it rides like a mountain bike. Chainstays are heat-treated for durability. It’s got 51mm I.S. disc caliper mounts for braking satisfaction. The fork can be replaced with a 100mm-travel suspension fork, but we’ve maintained good standover clearance, Clarence.
After many years in our line-up, it may seem odd to keep the 1x1 around. 26˝ wheels aren’t as popular as they once were, at least here in the U.S., but 26˝ is still a very capable wheel size, and works especially well on smaller frames for shorter folks. Plus, the 1x1 handles great, and can be built up a hundred different ways. It makes as good a street bike as it does an off-road bike. You could build it with 65mm Marge Lite rims, or 50mm Rabbit Holes and have yourself a mid-fat. The possibilities boggle the mind. We sell it as a frameset. The finish, as on all our frames, is durable powdercoat
