@dan28 - thanks for the offer, looks like Charlieboy has the spares tho.
@Charlieboy28 - brilliant, yes and yours is a much better picture; couldn't for the life of me find one like that; my googling skills are obviously weak! It is the centering sleeve I need, def not a race (which my pic does look a bit like). Colour doesn't matter; black or silver, pink, paisley, puce or glowing beige!
Are you happy to post in return for Christmas goodwill, or can I offer you a Kona racelight straight bar or some old cantis in return?! I've got an old V brake if you fancy one..?
Nice one,
Sam.
