    My RMX is HEAVY!

    At the start of this season, I got an RMX for pretty cheap and have been happy with it up until now... or atleast until last week. I hopped aboard my friends sub-40 pound Sunday and it felt like I was pedaling an AM bike. So my question is, what is the stock weight of a 2006 RMX 1.0 and what can I do to lighten it?

    Heres what I plan to change so far:

    Fork: Boxxer Race or Team (with Boxcart internals. I found a great deal)
    Tubes: Tubeless
    Cranks: Saint
    Cassette and RD: Shimano 105
    Chainguide: LG1
    Saddle: Sette Ti
    Pedals: Mallet M

    To see the components, go here: http://bikes.com/bikes/2006/rmx/rmx-1.aspx

    Mavic Ex 325s. They're stock and unbelievalby heavy. I looked for an affordable wheelset but everything is a little out of my price range.

    I don't know the weight but personally I love the Sram X 9's

    no cable loop to get caught up on a rock or branch and a hevier spring that one that helps against ghost shifting and two doesn't bang the frame as bad as the Shimano stuff
    the trick is ENJOYING YOUR LIFE EACH DAY, don't waste them away wishing for better days

    The ti rails will snap into, the chromoly rails will bend.

    Been there and done both.

    Tires and tubes are a big one. If you can reduce your rolling weight it will help a tone, when on the train riding.

    The tubless option is one of the best.

    An other area to look at is bar and stem.

    Wheels, tires, and tubes will give you the biggest payoff. Not only do they lighten your bike, but rotational mass has more effect on the feel of your bike than anything else. I don't know what kind of trails you're riding, but you can probably get away with lighter tires than whatever you're running. You might have to pay with the occasional pinch. But I think it's an overall gain. That said, I ran Kenda Nevegal DH tires with fat Kenda tubes at Downieville last weekend and never worried about flats. It was awesome.
    Back of the camera, back of the pack.

    I think here's the order of what I'm going to upgrade:

    Fork: Boxcart Boxxer
    Wheelset: dunno, was thinking King Earls but have heard problems about the hubs. Maybe the DH tubeless wheelset from ride-this? It's got Hadley hubs (sweet) and Mavic 823 rims.
    Tubes: Go Tubeless
    Pedals: Mallet M
    Bar: Sette F/X2 31.8mm Carbon Riser Bar
    Stem: Thomson Elite DH
    Chainguide LG1 with a thin, light bashguard from metal shop

    I'll probably just take it from there. Hopefully, by the end I can get it down to about 42 lbs.

    They're lighter than the RaceFace offering.

    I think the new Truvativ cranks may be lighter. If you're not super hard on parts, you could get away with XT or Atlas cranks.

    As mentioned, wheels, tires, and tubes will make the biggest difference.
