    Triple front derailleur suggestions needed

    I'm trying to get my '84 Schwinn LeTour better equiped for loaded touring and replaced the 52/39 double crank with a 48-38-28 Shimano mountain crankset. I had to replace the BB spindle with a (yes this is correct) shorter one to get the chain rings closer and within range of the FD. It has a Suntour Mountech FD which I thought would handle it fine but I'm having problems getting it to drop to the granny gear.

    I dropped the FD on the seat tube to get a closer clearance on the big ring but it has a long cage and just barely clears the chain stay when it moves in, so I'm as low as I can get. It is only about 3-4mm above the big ring so that should be in the ballpark. It has Suntour Symmetric DT shift levers.

    Anyway I'm thinking I will possibly need a shorter cage, tighter arc mountain derailleur to get me the chainstay clearance. Any thoughts on a 1 1/8 clamp bottom pull FD that would work and have a wide throw? This will be somewhat of a utility tourer so I don't want to get anything pricey - just something dependable.

    I have a Bridgestone 400 with the stock AR FD and that works fine with a similar ringed crankset so this kind of threw me for a loop. Did the Mountech come in double and triple versions?
    Thanks -

    Alpina Front Derailleur
    Same performance level as the CD, but designed for triples. Will work with standard road triple cranks, but it is optimized for smaller rings such as 48-36-24t or 50-36-30t.

    • Braze-on style, but this includes an adapter clamp for 28.6, 31.8 or 34.9mm.
    • Two models:
    Alpina-d is designed to work better with Shimano's drop bar/STI shifters.
    Alpina-f is designed to work better with Shimano's flat bar road shifters.

    Looks good but a bit more $ than I'd like to invest in the bike. I should have noted I'm more interested in an older model that I could perhaps find used. I'll keep this in mind though.

    How about a Deore, or Deore XT?

    I use a Shimano 105, "5503" on my 50/39/30 matching 105 triple crankset. It shifts perfectly. It might also work well on a Shimano mountain triple.

    I've found several on ebay for my project bikes and work great. They can often be found in 1 1/8" clamp size and are usually inexpensive.

    I am using a RSX FD with a matching triple crankset (50-40-30) without any problems. They show up on fleeBay pretty regularly. I have a spare one here, but postage from AU would be more than the derailleur is worth. You may need to change your RD to a long cage as well.

    I use the Shimano XTR FD-M953 Front Derailleur - on my Ultegra triple crankset. Works beautifully. Although it isn't supposed to.
    How do you keep an idiot in suspense?
