so i'm about to replace a 151 bcd campy pista crankset with a 144 bcd strada crankset (both fluted kind) for a couple of reasons. does anyone know if the chainline on the outer ring of the stradas will work well with the existing 109 pista bb before i get to swapping everything out and finding it doesn't?

yeah they are basically the same crankset but the strada has a shelf for the inner ring
this would be the only problem; you might have some chainstay interference

you can file the spiders shelfs completely off or even leave a littel bit if you ever want to run them as strada again

are you selling the 151 set ?
plz let me know if yes

trons

oh yes, the old chainstay clearance issue. eyeballing it i think it's going to hit.... to file or not to file

I've upgraded from Campagnolo 151 strada to campagnolo 151 pista; the pista ring is something like 2 or 3 millimeters on the outside compared to he strada.

That's because the arms are beefier on the pista.

trons

yep. i threw the strada drive side arm on there and it looked like it wouldn't clear regardless of whether i filed it or not. oh well.

hmm i never noticed any differences but maybe it's a 144-151 thing ?
