Side note — may I ask should I be paranoid when riding on dusty roads where debris falls into the “exposed” free wheel - it will greatly increase the wear? Not to sound silly I am thinking of trying to have something sit over that exposed part - so that it does not get all the loose road grit trapped on the cogs? Every now then I spray the grit out and air dry.
Anyone can advise?
I bought a spare free wheel - yes not cheap - and thankyou for this thread I think I have the Mk2 version.
