I'm thinking about running a 1/8 DA chain wheel (49) and 1/8 Campy rear cog (15) on my bike.
Given the teeth are slightly different (DA has sharper teeth and Campy squarer, I'm wondering if I should have them match Both DA or both Campy.
This is irrelevent, since the chainring and cog do not mesh directly, and the chain just needs to also be 1/8".
