So I finally pulled the trigger on a cross bike (super stoked) but to do it I robbed all of my parts from my road bike to get it rolling. I have a 105 Compact crank (50-34) and was wondering if I could buy the CX-70 chainrings and they bolt right up. I believe they are both 110 BCD, has anyone tried it? I don't want to buy a new crank particularly. Thanks!
