I'm really happy with 50/34 on mine, to be honest i end up using the 34 & 11/12 a fair bit as the chainline is straighter than on the big ring at the larger end of the block. I do end up changing at the front far more often than i do on a bike with 53/39 Centaur/Daytona 10s but the Athena FD shifts far, far better than the older front mech so its not really an issue
