ok, I've got a BB mounted Superstar plasma and I'm putting it on a Cove G spot.
73mm BB and Shimano Ht cranks. So I've removed the drive side spacer and put the chain device on. However when I put the cranks back on it fouls on the granny ring threads. Even if I file these off it will still foul the middle ring. I've got an e13 bash on the out side. how do I fix this? do I need longer cranks?
