Make sure when you get the replacement that you get everything. Should come with a crank, BB, front der, and a chain. Last two of these I dealt with one shop lost the BB and the other shop kept the chain and front der. I fix bikes for people who can't afford them and these kinds of losses suck. Shimano has begun shipping them out though. I got both sets in May though the two cranks were dropped off 6 and 15 months prior.
