I’m selling a pair of XT cranks (M780) 175mm length as they are surplus to requirements. Originally they were 2x, but I’ve been using them as 1x. Will include a 30T Hope ring, but it is pretty worn and won’t take a new chain so is probably not much use! Cranks are in good condition, just a few superficial scrapes and marks from riding.
£40 posted.

If they'd been 170mm, I'd have bitten your hand off...
