So, my current setup is 39x16 on 170mm cranks. I had decided on the 165mm Omnium cranks, but the one thing I don't like is that it comes with a 48t chainring. The Miche Advanced comes with a 49t chainring, which would allow me to keep my 16t cog. I could purchase a 47t chainring for the Omniums, and that would put me approx. $20 more than the Miche Advanced set. All of these options would give me a significantly higher number of gear inches which made me think that I may need to purchase a larger cog, but I don't really want to do that. Trying to gather some opinions on these two sets. Is one clearly superior to the other? Thanks for the help.
