Greeting v4 lovers, completed chain and sprocket replacement yesterday...-1 on front to a 15t as most people rave about the mod thought I'd try it.. Will let you all know the findings.
Went out on the bike after the mod for the first time Sunday, it's mental properly mental in track mode point and shoot jobby, not had a chance for much riding it yet to properly give my verdict but can do 40 in 6th no problem pick up seems rapid and for the riding I do it's possibly better suited slightly geared down
