    How to reduce weight on Rumble-fish

    I have a Rumblefish Elite that I'm looking to lighten up. Interested in hearing what to replace to get the greatest bang for the buck and reduce weight.

    Here is my build: Rumblefish Elite - Trek Bicycle

    Thanks for your feedback.
    Adios,

    Love the raw tint trek does on thier bikes. We got a 2012 ex9 sitting at the shop in the raw tint looks sooooo sick!! Good luck losing weight... bike is kinda ment to be a heavy duty all mountain/trail type bike. Carbon bars/stem/seatpost but that wont make a huge difference. The crank on that thing is heavy.. go with a xtr that will slim her down some. And yes wheels, thoes dusters are heavy..

    Well thats the thing.. you actually riding some serious stuff with it? Cause light and strong are kinda conflicting attributes when it comes to wheels. DT makes some new AM wheelsets I think come in around 1700g. Bonty race lite and racex lite are pretty light but Im not sure how they would hold up on more serious terrain. The bontys use DT hubs too, they are a nice product.

    The dusters are strong wheels, but definetly not light.

    How do you guys think some Chris King hubs would hang on the RF?

    They would hang just fine but you are not going to realize significant weight savings with them, the dollar per gram ratio is pretty high.

    Best bang for the buck in weight savings is simple. Two steps.
    Remove your wallet from your back pocket.
    Hand it to me.

    There, you saved at least a pound. And it was probably cheaper than bike parts. Now go ride your sweet azzed bike.

    OK, I rode this bike at the LBS, and its heavy. Big wheels take more to get going too then 26". We put the bike on the scale its over 31 lbs. Now to spend all that money and now to spend more to get it lighter well that just sux IMO.'You can go to carbon bars,seatpost, pedals get some Shim XT cranks (XTR) are way too much $ IMO.
    U can swap out the wheels with some lighter ones too. Get some lighter Magura Brakes if you like. But all that is a lot of cash my friend.
    Just the burden of the beast with full suspension bikes, unless you fork out $5k out of the gate.

    I would start with lighter wheels and tires. Best place to drop weight. Especially on a 29er.
    Hope hubs and Stan's Arch EX rims make a strong lightweight wheel set. A complete wheel set can be built for about $600.

    +1 CK is not lighter If you want light then check out American Classic hub, they are lighter.

    arch-ex laced to dt swiss 240 hubs, easton haven bar, thomson post, esi grips, tubeless, slx cranks. that should drop a couple pounds at least, and you will still have a pretty burly build.

    Beside tires and tubes it's about a thousand per pound, how many pounds do you want to loose?

    Wow this is a great thread with good advice. I think I'm starting to get the picture......either the bike is going to be bomber or its going to be lite and a little more fragile. I think I'll do something with the tires, then re-build the motor in the gym over winter ha ha! But you guys have really opened my eyes.
    Adios,

    I'd swap out the frame with one of those Chinese carbon jobs.

    Well, if it helps, I have my 17.5 Rumblefish in the 27lbs range, including a dropper seatpost.

    The biggest weight savings come from the wheels/tubless tires (Swapped to Easton Haven's)
    2x10 drivetrain (SRAM X9 crankset + XO cassette) also droped a little weight
    The bar/stem/grip combo (Easton Haven/ESI Chunky) dropped more.
    The sadlle (Specialized Henge Ti) is a bit lighter too.
