What kind of clutch is this?

Just a good old Comet clutch. What is the bore and pitch? I would be interested in a trade for the Tri-stars depending on those factors. The extra shipping to Canada could be worth it if it's what I hope it is.:thumbsup:
A two speed clutch has two sets of sprockets "teeth" where the chain would ride on. Yours only has one set. The other set you see on yours is only for the outer bell of the clutch to be held in place.
