So you got a great deal on a diamond ring and now need a fiancÚ

I’m not a pista guy so my apologies if my general info does not apply to pista. The typical process is to land on a crankset and then match the bottom bracket. Suntour Superbe cranks would be the obvious choice but even this is a little murky when trying to figure out which gen cranks go with which bb. And as you’ve already discovered, Suntour taper is different, reportedly being interchangeable with Campagnolo. ISO or JIS cranks may work but one will likely bottom out and the other will seat further out and effectively widen your chain line.

You can scour velobase.com to find possible Suntour and Campy matches. Or you can trial an error by installing random cranks and measuring chain lines. If it were me, I’d go with the cranks I want and match the right bb. Good luck
