hey wondering if anyone knows what the specs are of a stock 2002 bianchi pista, particularly the bb and crankset. i'm trying to piece parts together, and am having a hell of a hard time trying to get a decent chain line. i'm thinking that maybe knowing the specs of the stock bb and crankset can shed some light on this.

currently running off a shimano 600 double, mounted on the stock 68x107bb, but it's f-ed the way up. only the inner ring is lining up (barely..off by 2mm), and even that is a 39t. if i go higher, up to 44t, it'll definitely get in the way of the chainstay...

in brighter news, if anyone can recommend a good crankset for the 02 pistas that's worked for him/her, i'm all ears!!

much thanks!
