Thanks for the replies! Will look a the ideas suggested.
What is the largest rear sprocket I could go to without changing the standard chain?
David thanks,I think you may be able to span the two teeth with the stock chain. I think that I have done it before. On the racer I have a new chain for every two teeth.
