Description

In addition to being a stellar SS cog, the cog base width (where it contacts the freehub body) is 4.35mm, so you can stack a few of them up and use a 9-speed shifter for a simplified multi-speed drivetrain. This width also prevents it from ruining the freehub body as a result of digging grooves into it like skinny stamped cogs have a tendency to do. Surly cogs are machined from SCM415 CroMoly steel, then heat-treated for toughness and chrome-plated for surface hardening and enhanced chain lubricity. Our cogs will work with 6-9-speed 3/32" chains, although we recommend the inherently updated quality of an 8 or 9 speed chain. They are also available in every increment from 17-22t, so you can select that perfect gear. Note: Teeth profiles are straight forward, making them ideal for Single Speed applications however, with no twists or ramps etc the gear shifting will not be as slick as with regular Shimano cogs when used in a multiple cog line-up. Note: When used in non-9 set-up, additional Cassette spacers will be required to fill the cassette body.
