I'm currently running a stock 630 41T rear sprocket. It is really close to the lower spring platform of my shock. After doing some reading I'm thinking of exchanging it for a 630 38T. Not only could it fix my problem but it could tame the wish of wanting a 6th gear. I know it will be slower off the line but this is more of a cafe cruzer than a cafe racer.
Anybody know the difference in diameter of these two sprockets?
Thanks in advance.
Oh BTW this is on a '78 so sprockets are spaced out OEM and I'm running a 160 rear tire. No room to slide the sprockets in.
