Surly Single-Speed Kit, Spacers and Lockring
We now offer a single-speed spacer kit that allows you to use single-speed cassette cogs on the freehub body of your multi-speed Shimano cassette-compatible hub.
With the supplied selection of anodized aluminum spacers, you can attain a perfect chainline to compliment your road, track, or mountain crankset. Our large-diameter stainless steel cassette lockring holds everything together and perfectly matches the outside diameter of the spacers. Plus, it matches the machined shoulder of our single-speed cassette cogs (not included). The lockring is machined to utilize a common Shimano cassette lockring tool for installation and removal.POA
Surly Stainless Steel Track Cog Lockring 1.29" x 24 tpi Left-hand Thread
CNC-machined from premium stainless steel...no flaking chrome or rusting. We’ve improved the design to increase thread contact. It’s now a full 5mm thick, plus a lip (.65mm extra) to maximize thread contact on all compatible hubs. Fits English lockring threads (1.29x24tpi LH) to work on almost all track hubs available today except Campagnolo (1.32x24t LH) and French (33x1mm LH).POA

Our cassette-type cogs are designed to fit on standard Shimano compatible freehub bodies. These cogs have a tall tooth profile that is essential for preventing chain skip from the extra torque a singlespeed drivetrain encounters.POAPOAPOAPOAPOAPOAPOAPOAPOAPOA
Our track cogs are designed to spin onto standard ISO-threaded (1.375" x 24tpi) hubs, so they will work with most English, Italian and Japanese hubs, including the Surly New track hubs. The thread base is 7.4mm wide for maximum thread engagement while maintaining enough room for a track lockring to thread on. Like our cassette-splined cogs, these are made from machined, heat-treated and chrome plated SCM415 CroMoly steel, so they are tough and long lasting. Track cogs are available in either 3/32" or 1/8" tooth thicknesses and in every size from 13-22t.POA
