Front Mech + smaller chainrings question

Posted on
  • My current front mech is dura ace and the range for the big ring is listed as 50-56t (I have a 52-39 on atm).. will it work ok with 48-34 ?
    Thanks!

  • You are pushing it a bit, and might have to set the mech slightly higher than the correct mech for a compact
    Firstly you may get the mech rubbing on the chainstay when using the small ring, then the chain is more likely to come off the big ring especially if you change at the front when the chain is on a smaller cog at the back, but with careful set up and a bit of care in use you will be able to get by
