    Soma Juice 29er sizing

    I have been going back and forth between a L and XL with my current Felt bike. I stumbled upon the Soma Juice frame and feel in love. I think that little frame drop it has would be the perfect happy medium between a L and XL. My question is would all of my components fit on the Soma frame?

    2013 Felt Nine 60 - Hibachi
    Rockshox SID XX w/remote
    XT Crankset
    XT Cassette
    XT Front and Rear Derailleur
    XT Shifters
    XT Brakes
    KCNC f/r skewers
    Stan's Arch EX 29er wheels
    Schwalbe Nobby Nic tires
    FSA SL-K stem
    Truvativ Holzfeller riser bar
    Ergo grips

    The general component models don't matter so much, you need to understand the key dimensions on the Juice frame (which I have, BTW):

    27.2mm seat post

    28.6mm front derailer clamp, top pull

    30.0mm seat collar (I think)

    non tapered 1-1/8" fork, regular (not integrated) headset

    73mm bottom bracket


    Looking at the Felt, looks like a tapered steerer, so that's a new fork and headset. The crank and bb should fit OK, but you'll need a new seat post, clamp, and front derailer. Everything else should carry over.

    I'd have get a new fork altogether? There is no adapter of any sort that would make my SID coming from a tapered head tube work on this bike?

    No, the thick part of the fork is simply too big to fit.

    I saw that site. Thanks. Trying to determine sizing for the Juice but can't find geometry to save my life. The link on Soma's website is valid but the specs simply dont load.

    What about headset? Just keep what came on the Felt or worth the upgrade for a Chris King? What are key measurements when shopping headsets?

    The Felt's headset won't fit, since it's made for a tapered fork.

    You need a normal, 1-1/8" headset, external type. Like this one.

    I like the Cane Creek S3 (now called the 40 series) headsets. Cheapish, smooth, reliable. I can't see paying 2.5x as much for CK.

    Yes it will... now you need a non-tapered fork to go in it.

    What does a 100mm fork do to the Geo?

    Here's the geometry. I'm just finishing up a small/16" Juice as a singlespeed myself!
