sorry i dont know how u worked that out, al i can is this which is for £39.
can u tell me where i can get the dx cog cheapest, cos i cant seem to find it for a mtb.
so the cog doesnt dig in using the shimano dx, do u really need those ss sleeves then? wat they shud to is make them with the teeth bit to attach to the freewheel and then bolt althe way through the cog so then there wont be any damage...less pressure and stuff.
anway fanks
