FE-SSK 1.8 (Single Speed Kit)

The FireEye SSK (Single Speed Kit) converts a standard 8/9-speed shimano-splined cassette hub to a single speed hub in a snap. You don't even have to change your chain either! The SSK 1.8 comes with a 14t, 16T, or an 18T cog, 3 different sized alloy spacers to provide proper chainline alignment, and a lock ring to keep everything locked down tight. You'll be pleasantly surprised how easy and enjoyable a single speed can be.
