    New question here. Which space saving front derailleur?

    I'm struggeling with the combination short chainstay/fat tires.
    Which clamp mounted front derailleur is the most space saving of all FD's on the market? (From Sora to XTR, Shimano or Sram…whatever)

    I had a similar problem on a 10 speed HT 29er, short chainstays and trying to run fat high volume tire. E-type Shimano XT gave the best clearance but still not enough to run a true 2.4 for me. 2.25 was the biggest tire I could run with a FD. I ended up going 1X10 to run the big rear tire.

    XT M750 High Clamp FD has been the one for me with the least profile, very low profile indeed, I used it on my Paradox V1 to help. Another trick you can use if you're using an external BB crankset is to just space the crank another spacer out (2.5mm normally) that will also give a little more clearance, but depends on your chainline - prob not best with a 3X setup, works fine with a 2X setup.

    I would go with a Direct mount adapter + derailleur. Problem Solvers does such an adapter.

    Alternatively, a bottom-swing Shimano gives good clearance and if you have a top pull cable routing, you can saw off the dual pull arm to gain even more space.

    What frame are we talking about?

    Where are your clearance problems?
    ST clamp?
    Cable routing?
    Tail of the cage?

    Thanks for your answers. A lot of good tips here.
    My frame is a GF X-Cal 2009 that I recently purchased, and I enjoy ridning with RaceKing 2.2 Race Sport edition for light gravel racing etc. The "hinge-mech" of the FD is slightly touching the outermost diameter of the tyre threads, unless I'm using the 44t.
    I have considered to just go for 1x9, but I think I need at least the 2x setup for my kind of riding. 1x10 or 1x11 is not relevant, since this is after all only my backup bike.

    What is the "hinge-mech"?

    Hm, difficult to find the right words, and I´m not able to post a picture right now. Anyway, it´s the part of the FD that´s closest to the tyre. By the way I´m using a SLX now and I´ve tried to modify it a bit with a file...

    Agree, post a pic of exactly what's rubbing. Also helps to know exactly which FD you have, do you know which SLX version it is? They vary quite a bit in the few years that SLX has been out.

    Well, any part that is rubbing the tire is closest to the tire. Could be any of the things I asked about earlier.

    hello there
    i have the same problem with my trek wahoo (hard tail) even i am a beginner in such a mechanisms.

    so do you think a bottom swing (Shimano XTR FD-M961 Front Derailleur, Dual Pull, Bottom Swing, High Clamp) will save enough space? like 1/2"?
