    Scalpel 29er upgrade question ???

    I have a Scalpel 2 29er. I want to upgrade the cranks and the front derailleur.

    Will a XX front derailleur work (I know it needs to be an S3) ?

    I want to upgrade to a set of Hollowgrams 39X26 ... will that derailleur work with those cranks, with that teeth count ???

    The majority of shifting happens at the rear derailleur, I'd upgrade that long before the front der.

    XX will work. That's what I have on my Ultimate. Works terrific with the XTR shifters.

    Is that the same teeth count as your Ultimate ? I ask because I've heard that the XX and the XO FD's need to be with a certain set up regarding the size of the rings. Some sizes won't work with either model.

    I think that all of the Ultimate's came with 39/26 XX rings. You may be right about the rings and FD sizing.

    The 2013 Ultimate's come with XO FD .... which makes no sense to me for an $10k + bike !!!

    Nope. Mine shipped with XX FD, XTR RD, XTR cassette, and Cannondale SISL crank with 39-26 XX chain mounted on the Cannondale 120mm-80mm spider. I set my Scalpel up for 38-24 rings by using the Cannondale 3x9 spider with XO rings and a bash guard.
