Maybe a little off your aim, but I've had my Ultegra 9 sp double running 38/50 rings for months now, with no shifting issues. My new ride has the Shimano compact with 10 sp Ultegra and shifting is just fine - when you look closely at the compact big ring, you can see where they put serious engineering into the ramps, pins and teeth shape of the 50T ring to get good shifting performance - subtle points, but obviously they add up.Ryan said:Does anyone know if you will be able to use the new FC-R700 compact crank with Dura-Ace 9 components? I currently have DA9 Front Derailleur, DA Rear Derailleur, and a DA cassette.
I did a seach but couldn't find anything.
Thanks in advance.
