Just replaced a Tiagra 4500 chainset that someone had borked all the crank bolt threads on, with a new Claris one because that's all I could find with the same ratio. It's a road bike, which inexplicably has a MTB HT2 BB in it. The old crankset had a 3mm spacer on the NDS, and the new crankset comes with the same spacer. However, I cannot get the NDS crank arm on at all with the 3mm spacer in place. If I take it off, the crank fits as I'd expect and there's no play.
I assume the spindles are different length for some reason? But why would the new Claris one come with the spacer?
