    Help me lighten up my new Arc Carbon

    Just finished putting it together yesterday. Went for my first ride today. It's a little fatter than I expected, but is an amazing ride. I know the wheels are a big limiting factor. It weighs 22.95lb as it sits right now with pedals. Down the line I'm going to build an ultra light wheelset but I'd like to get it close to 22lb without doing that if possible.

    Help me lighten up my new Arc Carbon-photo.jpg


    The build:

    Large frame
    RS XX world cup Sid fork
    Thomson X4 stem 90mm
    Easton Haven Carbon bars
    XTR trail brakes 180/160 xt ice techs
    Easton Elite Seatpost
    Specialized Phenom expert saddle
    XT race pedals
    X01 drivetrain (XX1 cranks)
    Flow EX wheelset
    Ardent 2.25/Ikon 2.20 setup tubeless


    I'm thinking of swapping the stem and seatpost with a syntace p6 and F109. Also thinking about swapping rotors. Anything significantly lighter in 160/160? Then I could drop the adapter also. Any other ideas? Going to pickup a set of Enve wheels in spring that will hopefully get me down to 19lb with some lighter tires.

    you're right lol. With stem/post/front tire swap i should knock off .75lb

    I think thats pretty good with a stout wheelset.

    The wheels will be the only place you can lose any appreciable weight. Anything else (stem/seatpost/front tire) will be throwing money away without any performance gain - actually a performance loss w/regards to the front tire.

    I really like the ardent on the front, it's nearly 900g though (lust/ust). I really like the ikon on the rear, thinking about tryin a 2.35 on the front

    I've got ENVE wheels on mine. It weighs about 19 pounds, so yeah, that will do it...I also have ENVE stem, post and bars, but their weight is probably similar to your existing parts.

    The small changes will be irrelevant compared to the wheel swap when you do it. Mine is almost identical except full XX1 and crest wheels. I swapped to the Ritchey C260 stem and Syntace flex seatpost but pretty small weight gains. I'm considering the new carbon wheels from Giant actually.
