    FTM w/ 140 or 120??

    Building up a small FTM for wife who only weighs 115. She had a 120 Float on old Motolite and seemed to work perfect for her. Have the option of putting on a 140 Float on new bike or sticking with the 120. Any opinions/suggestions would be great.

    I might be totally wrong, but I thought the FTM's geometry was optimized for 140mm forks, and while her size/weight might not warrant the extra travel, the extra axle-to-crown height makes a huge difference on the front end feel and geometry of the bike.

    I originally had a 100mm fork on my ML, and while it wasn't terrible, it handles much better now at 120mm. It seems these bikes are designed with a "sweet spot" in mind.

    Just my 2.

    Yeah, FTM geometry is optimized for 140mm travel, so I would think 130-150 as the range. 120 might work if you wanted to make a fast cross-country/climbing bike, but it would make the bike feel sketchy going down.

    (I ride a FTM, 140 Fox float.)

    The Basic Build Kit that came with the 2009 FTM's was spec'd with the F120. Mine is like this and I do not notice any ill effects from it. Would like to try a 140 on there, but the 120 works just fine. Bike is very nimble as it is.

    My wife rides an XS ftm with a 140mm revelation team up front and loves it. She climbs just as well as she did on a 115mm fork she had on her old bike. I really like the revelation for her becuase I can increase the negative air to help with the small bump compliance.

    My 09 came with a 140 talas and I wouldn't have put anything less on it. I'm actually thinking about building another one with a 160-130-100 talas.

    I got a TALAS on mine and I ride it at 140 and rarely go down to 120.
    Your bike is not the only thing that needs maintenance!

    I sometimes wish I had bought a Float.
