The FireEye SSK (Single Speed Kit) converts a standard 8/9-speed shimano-splined cassette hub to a single speed hub in a snap. The SSK comes with two (12/13T, 14/16T, or 16/18T) cogs, 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.
