Has anybody out there used Manic Mechanics sprocket adapter on a Schwinn Riverside? Or any 7 speed 26in Schwinn for that matter? I understand its all machined to your bikes specs but has anyone out there had any spacing issues or issues at all? I'm looking to place an order for an adapter and a new 36t sprocket by this Monday because my bike failed me yet again when the chain snapped off for some reason while I was going back home from a 1 hour ride.
