Thanks for the reminder, yes I did look and its the very late Monster engine that would have run 15/46 gearing as a standard road bike

So sprocket oprtions I would be looking at are
Fr 15 Rears 44/45/46/47
or
Fr 14 Rears 41/42/43/44

So as you have a 14Fr then pop down Swindon way and get those two alloy renthal sprockets off Gilps
