    LHT front d. compatability

    Hey, thanks for all the help so far on my LHT build. Trying to find a suitable front derailleur,
    I'll be running:
    sugino xd300 26/36/48
    deore hg-50 11-34 cassette 9 sp
    xt rd-m761 rear d.

    Looked at the 105,but 5503 is discontinued and the updated model doesn't work so well with this set-up according to my LBS guy. How about this:
    Shimano FD-R443 Flatbar Triple Front Derailleur, 28.6mm, Bottom Pull, 9 Speed, Silver
    Looks like it'd work?....
    Thanks for your time!

    The Tiagra one is actually spec'd for 48t chainring, not sure about the others. I hear that's not so important, at least w/ continuous/friction shifting... What makes a FD flatbar-specific anyway?

    addendum

    oh yeah, I forgot to mention that I'm doing a flatbar setup up front and dura-ace down-tube shifters (friction for front d.).
    thanks,

    it won't work because of the cross-chain? Or what did the LBS guy say?

    I just built up an LHT with a 105 double front and and 11x34 cassette in the back... it works fine so far. I can't shift into 53x34... not that i would anyway, but the chain i have is too short.

    Here's what's on mine:



    I'm also running a 9-speed rear:



    But I'm using bar-end shifters:

    Since you're going with a friction front shifter, any derailleur will work. The "updated 105 model won't work as well" comment from your bike shop is related to its use with indexed shifters. If you use the 105 with rations that are non-approved by Shimano engineers, you will have to trim your left shifter once or twice. No problem with bar-end or downtube shifters.
