Hmm, thought so, does that mean I cannot buy 34t and 50t chainrings and fit them to my Veloce 39/53t spider? as the BCD is indicated as 110 on the compact and 135 on the standard.
I was considering going compact on the winter bike, by swapping the centaur chainset from my best bike onto the winter bike, and buying a nice carbon crankset for the best bike.
Just looking at best VFM options .
