Thanks
I have a road campagnolo that is 147mm q-factor on a 102mm bb so cannot get narrower. Campagnolo pista isnt cheap.... ?
Im thinking about some old shimano road square taper and then putting it on a 103mm BB. Hmmm. .. for cheapness!
This is exactly what I did for 1x10 for CX. I went with Shimano 600 and a square taper bb (107 IIRC, 103 was too narrow around the 38t chainring and chainstay).
It's slightly narrower than the regular Shimano road stance, which is nice.
Campag and Miche are narrow. Not sure Miche actually ends up 'narrow' if you use a 110mm spindle though.
