Condition:
Well used but solid and straight crank set. Lots of rubbing on crank arms to annodisation from normal use. Left arm is slightly newer than chain side arm as the original left arm developed a hairline crack and was replaced under warranty within the first year of ownership - hence a slightly different rubbing wear rate.
Chainring was replaced quite recently - can't remember when but it's has perhaps 10-12 rides so very little wear.
