    Help Me Lighten my Ride

    I'd like to up grade some parts my '05 Specialized StumpJumper 120 (dualie). I ride xc, roots,rocks and logs, weigh 220 lbs. I like to do small drops 2-3 feet. I'm looking to lighten up the bike some. What upgrades would you recommend considering my weight and riding style.

    More info would be helpful.

    What parts are on the bike? A spec list would helps us know what we are dealing with. Also check out the FAQ's that are always the first post in the forum. Lots of good advice. If you really want to get replys take a pic. I click on any thred that has that little camera thingy. Best of luck with the Stumpy. Buy one of the new carbon ones and it will be lighter for sure.

    XT cranks w/ x-type BB (assuming you have Hollowtech I Octalink)

    lighter wheel set (MavicCrossmax XL or equivalent custom build) if you go UST rims you can run tubeless to save a little more weight.

    XT cassette (assuming yours is LX)

    start with the basics
    pretty much all of the "house" components like the saddle, stem, seatpost, handlebar are all pretty generic and in most cases they will be heavy....
    those shimano 520 pedals are porkers too.
    replace the tubes with maxxis, panaracer, or continentals lightest version and youll save atleast 100gr. right there.
    Specialized tires are decent enough, but theyre soft, wear quickly and typically are pretty slow rolling....for the most part theyre fairly light, but there are much better alternatives out there.

    start with that....

    I agree with Jersey

    That your "house" componets are heavy, but personally I woiuld not start there with upgrades. The goal of lightweight parts is high performance, and while you will save considerable weight swapping bars stems posts etc I doubt you will feel the difference from a performance standpoint.

    lighter wheels, tires, tubes eic will shave weight, and make your bike quite a bit faster due to the reduction in rotating mass. Light tubes are an option, but depending where you ride may be prone to flats. Personally I would get some UST wheels, and use them with regular tires and stans. Less weight and better flat protection.

    After you secure a fast wheelset I would think about the rest of your parts. Wait for drivetrain parts to wear out before replacing them with lighter options.

    Have fun, Pedal
