>>1318260>I assumed it was a standardized thing as they don't give the dimensions of these things.What you have bought is 110mm crank ( I assume ), but it also can be 94mm ( really old schoold MTB ). The other crank is 130mm ( or 144mm ). Technically you can adopt one to other, but not on that chainring. And even then - it is cheaper to just buy a new crank.
