I'm putting a like-new S-7 rear rim with a coaster brake on my bike; and I ran into a problem: The chain is way too loose. After a quick count of the teeth on the cog/gear in both the old rim and the new one; it appears that the S-7's cog has fewer teeth.
My question is... can I just swap the gears? They're both coaster brake models, and look pretty much identical.
Since it possibly makes a difference; the S-7 came off a Fair Lady (I think) and the old S-2 came off a Sting-Ray.
I just want to make sure before I tear it apart...
