- SSK-2 is a basic kit with clean, angled spacers, lockring, and 16T cog
- SSK-3 is Wheels Manufacturings top-end kit, featuring an integrated "guide" shaped spacer that helps prevent your chain from falling off. Same spacers, plus the "Guide" spacers, lockring, and 16T cog
- both kits fit Shimano and Shimano-compatible 8/9sp freehub bodies
- Cog works with single speed chain only
I run a 9 speed chain with both, however. I've found this option to be perfectly adequate for my needs (commuting).
Ridiculously easy to install (if you can change a cassette, you can install this product).
The steel cog is quite durable.
PROS: Easy To Install, Durable
The included cog is garbage though, as expected. Just grab a quality cog and you'll be good to go - there are enough spacers in this kit to get the chainline perfect.
PROS: Attractive Design, Strong Construction, Lightweight, Great Mounting System
The problem I encountered here was that the channel that the chain sits in (created by the two tall spacers that you put on either side of the chainring) rubs against the chain and makes a lot of noise. I took it to my LBS and they couldn't figure out a way to stop the noise or the grinding either, we ended up just taking off one of the halves of the chain guide.
Other than that noise problem, it's a great product, easy to install, easy to convert my 9 speed hubs to single-speed use, and now I'm cruising.
PROS: Lots of spacers, Easy To Install
BEST USES: Cruising, Road Biking, Casual Riding, Mountain Biking
Used my one single cog as theirs was pretty thin. But probably works fine.
No issues with popping chains. looks killer..
PROS: Easy Install
BEST USES: Mountain Biking, Upgrade
