Sorry for not explaining better!!!
Looking for a SS specific non ramped 21t cog that fits a shimano freehub :LOL:
 
Cheers anyway!!!
On a side note, how do you find your Karate Monkey??? I'm in the process of planning a build for one as a SS endurance race bike!! :D

What little time I've spent riding it has been fun. It's a bit heavy and slow steering but other than that... all good
