    Top-pull road triple FD?

    Here´s a good one.
    Does anyone make a FD, compatible with a Shimano triple road STI shifter, that´s top pull?
    I know I can get a problem solver pulley thing by the way.
    A Speen adaptor is another possibilty.
    Just wondered.

    I don't follow all the product offerings so I don't know if anything is out there. But I convert top pull bikes to bottom by routing the cable around the left chainstay and back up. I use a piece of teflon tubing to protect the stay, but cut a hole in the outside bottom, so it's not a sump for all the water the wheel sends to the open end.

    BTW- the right chainstay also works, but most FDs get in the way.

    I have a Speen adaptor on my cyclocross bike. I don't like it much. Way too difficult to get proper tension. I imagine it would be even worse on a triple.

    I'm pretty obsessive about all of the FD options that Shimano offers and their compatibility, but I'm almost certain that what you're asking for doesn't exist (top pull triple FD that works with STI shifters). Shimano does make a version of the cyclocross-specific CX70 that is top pull (there may be a cheaper CX50 version also), but that is double only.

    One option would be to use a top-pull trekking front derailleur operated by a bar-end or down-tube shifter. If you want to stick with the STI shifter, then you'll have to run a regular road FD with some kind of adaptor or pulley.

    There's also a trick of using a length of housing from the last frame stop to the cable anchor on the derailleur, while anchoring the inner cable to the frame somewhere below the der. I've never tried it, but with a FD close-enough usually works.

    Or there is a roller to fit on the seat tube , band clamps on below the FD above the BB.

    for what it's worth, I run a shimano top pull mountain derailleur with old sora shifters.

    it's not perfect, but it works... takes a lot of adjusting to get it to work well, and it noticeably rubs in cross chain situations.

    i'm running a shimano FD-M430 with ST-3400 shifters

    I tip my hat, sir.



    V-brake noodles are fodder for endless ingenuity...

    There should be an Olympic Games for cleverness, and coming up with new uses for V-brake noodles should be a sport.

    That's a gold medal effort, right there.

    AFAIK every left STI shifter is functionally identical to its double or triple brethren.

    I'm not sure if that's true of the older style Sora with the thumb shifters.

    I imagine all of the 10-speed STI stuff with the double levers it probably is.
