Took the 75s off my Bolt to put on my new bike, replaced them with Campy pista cranks, the only problem is now I'm having clearance issues with the chainstay and NDS crank arm. Would it be so terrible to put a slight thicker washer under the crank bolt to put the crank a millimeter off the stays? It's really a very small amount--enough to rub, but not enough to stop it, but it gets worse the more I torque it on (up to spec of course)
What you are suggesting won't change the crank position. What Bb is in there? Depending on what model campag cranks you have, the newer ones are for 111mm axles, where as 75's are build for a 109mm axle. If it isn't clearing you probably need a bb with a longer axle
