SURLY TRACK COGS / LOCKRINGS
SURLY TRACK COGS
Surly 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 3/32" tooth thickness and in various sizes.

SURLY TRACK LOCKRINGS
Surly track lockrings are CNC-machined from premium stainless steel...no flaking chrome or rusting. They'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).
