The Surly 1 x 1

Check out the Surly 1 x 1

The Surly 1 x 1 frame set is made from butted 4130 CrMo tubing with Sub 11.0 track-style fork ends. It's a great bike for singlespeed or fixed gear use, on or off road! (The bike pictured is our demo model, and we left the threadless steerer extra long so people of different heights can comfortably test ride it.)
This frame has very generous tire clearance for ultra-wide tires, even with fenders; fittings for cantilever brakes front and rear.
The Surly 1 x 1 is designed for a 135 mm rear hub, either a singlespeed MTB hub or a modified cassette hub.
This frame is also ideal for use with internal gear hubs, such as the Shimano Nexus or SRAM Spectro 7-speed or the Rohloff Speedhub 14 speed!


The bike shown above is equipped with a standard Shimano cassette hub, which has been converted to single speed by replacing the stock cassette with two Shimano BMX sprockets (permitting manual selection of gears.)	The "Fatties Fit Fine" frame/fork geometry makes these Avocet 1.95 cross tires look skinny. For mud or sand, you can fit huge knobbies with no problem.
