    Gram - lighten my mojo

    OK Gram, you're site suggests your using the mojo as a WW test bike, so how does one save meaningful weight on an xtr build without wasting the tasty parts it comes with (e.g. - I'm not going to trade in my xtr wheels).

    ...and yes, I realize the question reflects a lack of true WW dedication (which is why I post it here, not on that thread)

    Ok, first I need your current build list, then I can go from there. Also need to know your weight and riding condition (the type of trails you ride).

    Peace.

    OK.. not much to be done here without spending losta money for little gain..
    But here goes

    Fork: Mantiou or DT
    Wheels: Stan's ZTR7000
    Saddle: SLR (some go as low as 60-70ish grams)
    Shock: DT XR Carbon
    Tires: I think the Karma are a lil lighter than the SB8s (go tubeless with yellow tape.)
    Brakes: Hope Mono Mini Pro
    Pedal: CB 4Ti


    That's about it... Your build looks like it should come in at a smidge over 24lbs... is that too heavy?

    Skewers, look at kcnc ti QR or controltech ti bolt-on.
    Shifters X.0 twisters instead of XTR (need to match rearD too)
    chain: KMC X9SL
    Stem: no idea about the weight of the ibis stem, but as an alternative look at syntace f99 or kcnc sc wing
    Cable housing: alligator i-link

    Rotors ? Probably important at your weight. (must be nice I'm xc/all mountain marathon at 160 )
    http://www.gramslightbikes.com/2007/...-serrated.html
    .10 to .18 (I dropped ~.18 of a pound)
    .....and an occasional tap to un-warp to get started. Probably my fault on setup rotor bolt tightening.
    How bout bolt on rear wheel skewer for a few also.

    Not too heavy at all...I love it, but there is always something more to work on...

    Let me give it a try...

    EDIT 1: redid with weight savings (the numbers are ballpark for some of the items)
    EDIT 2: added a ** for ones that are best bang for the buck (and easiest to do) and one for the saddle *** cause they can be a bit pricey

    Easy and cheap (well relative) changes:

    Monkeylite SL bars -25g
    Alligator i-Link housing -21g
    Powercordz shift cables -18g
    **Ti bolt kit -46g
    **Plastic inserts for water bottle bolts -7g
    **Tubeless conversion -50g
    KCNC SC Wing stem ? (don't know the Ibis stem weight) -10g OK>ignore this one per Pocket Rockets last update
    Sram Attack twist shifters -40g
    **KMC X10SL chain (yea it works for 9 speed) -40g
    ***Saddle - various such as Selle Italia SLR -50g thru 80g+
    **KCNC MTB skewers -73g
    KCNC Ti Pro seatpost -30g
    **Alligator rotors (you have the center lock so there is a conversion adapter needed) -56g

    Expensive changes:

    Marta SL brakes -200g
    Manitou Minute MRD fork -230g
    DT Swiss carbon rear shock -70g

    Nice...I've got nylon inserts where I can, I think the next steps will be:

    -Saddle (phenom sl (not the lightest, but my crew is pretty picky and that saddle is getting great reviews)
    - Ti/Al bolts
    - Skewers - KCNC? - or some bolt-ons?
    - Going Tubeless, but need to experiment with this one, seeing which tires work well with the xtr's (and with or without an added strip, and which among the choices out there)
