Pretty much any 4 bolt chainring will fit those cranks.
Excellent, that's just what I needed to know
Thank you. For reference it's a 104mm 4 bolt I needed.
I had been looking at Chain reaction and sceen the deore one for about £10.99. A colleague at work said he has a 200KM one I can have it's he wants a 32 rather than a 36... so all being well I think I am sorted.
Many thanks chaps. Hopefully this will stop my knee from going double it's normal size again, after smacking it on the suspension strut from the cog slipping d'oh.
