    Front der arm rubbing tire (CX/Tiagra 4700)

    So I have this issue i'm just noticing with a Kenda Flintridge 35C and its side knobs rubbing the front der arm when in the big ring...that really sucks.

    Is there a different front der with less arm that would work with that shifter? Seems kinda big on this Tiagra 4700 series. Maybe i need to switch to older series? I really wanna be able to run tires around this size.

    yup, that's exactly why shimano ditched that long arm on newer DA groups and switched back to a normal one. It appears the other groups haven't switched back yet.

    Sorry, not sure what will work for. If we were talking Dura Ace I'm pretty sure a NEW 9100 would be the way to go.

    You might want to call Shimano about this one before spending. I'm pretty sure and old one won't be ideal but I could be wrong.

    Wow that really is long.
    Look at the 105 or Ultegra FD. They have shorter arms.

    Those won't work. The new 4700 group uses the same pull ratios as the 11sp groups. What Jay said about the 9100 der is accurate, it really is the only option until the new generations of 11sp roll out over the next 1-2 years. Luckily front derailleurs are cheap, and even though it's Dura Ace, it'll only cost you about $100.00.
