Hi Neil, Using a 13T front (not sure of that number) on a standard 38T rear gives same final drive as the 14/41 option - 138mph @ 11,000rpm. 14/41 is currently fitted to my bike but thanks for the offer. PS. still riding it like a banshee, novelty not yet worn off ! Whilst doing all this gear ratio checks and counting teeth I've since noticed that the rear sprocket has a few mm's side to side movement so I may be popping down soon for you to take a quick look over to see if all is OK.
