Thanks. I've actually managed to find an answer; the Sugino XDs I first tried were the triple forging (from Hubjub) and fouled the cup without even tightening the crankbolt. Then I tried the other XDs from my Inbred. These are the double forging and they fit with clearance, even when the bolt is mullered down hard.
So...I reckon most Sugino single or double cranks are OK.
Why use the 103mm? It weighs 148g (claimed 145g, but I trust my scales). That's half the weight of a UN54!
