7900 capacity help


I'm currently running a Ultegra 6700 50/34 11-28t setup, there's some play in the mech and trying to find a definitive answer if a 7900 SS will work with the above ratios.

    Yes. This reliable source lists max cog size as 28t and capacity of 33t, which matches what you need exactly.
  • Thanks was initially looking at the 6700 ultegra GS as that's what I have and the SS version not quite achieving the range.

    Seems like the dura ace 7900 is capable for what I need 💪🏽
