Wanted: Tiagra Shifter (compact double)

Posted on
  • Looking for a Shimano Tiagra (ST4500) double shifter (left hand break+gear) - mine has ceased to function.

    It is for a Specialised Allez 2009 with a compact double chainring. The bike was shipped with a triple shifter, which did use to work but I understand that this may have cause the mechanism to fail.

    thanks Nick

  • I've a 105 9 speed era double that'll work (same cable pull) that's in good order cosmetically and mechanically very good also, the compact bit you mention isn't relevant in any way shape or form just so you know, unlikely that it was anything to do with the orig being a triple as I've used a triple DA on a double crank for nigh on 7 years and it's only the actual pull across the rings (of the front D) that is a little different.
    PM me if it might be of interest

  • I have a Tiagra one - exactly the one you are after.
    I crashed my old bike on the right hand side and bent the other lever so this one is pretty good.
    Here are some photos:



  • sorted, thanks all
