    Whoah! 4.7lbs is REALLY light, even without a shock.

    Are you sure?

    I don't think you can weigh a dual suspension frame without including the shock. It is a non-functional frame, especially on the EX suspension design. If the shock is .45 lbs, a weight I have seen listed for the RP2, that would mean the frame weight is really more like 5.15 lbs. That is still very light, but is at least in a realistic range of accuracy.

    I tend to think the only way to weigh the frame, without serious chance of some error in calculations, is to strip the bike down and just weigh the frame (and shock) without anything else on it. If you try to use published weights on components, and compare that to the overall bike weight, it just won't work because those weights vary in reality with the actual components. When you start factoring in the possible range of variation on all the different components on a bike, you could get a pretty wide variation from published weights compared to what a particular bike actually weighs.

    The published weight for a 2009 Fuel EX 9.9 frame, as set forth in a review, is 4.92 pounds. It is hard to believe the 2008 aluminum version would be lighter than the new carbon version designed specifically to be lighter.

    I agree. I'm more inclined to believe that the Fuel EX aluminum frame is in the 6lb range, but was curious to hear how Byron weighed his frame to get 4.7lbs.

    the striped down frame was was 4.7 no rear shock, no headset,no seat post clamp. that was the reading at my local bike shop digital scale. I just hope their scale was accurate, but just for the record carbon fiber frames are not always lighter the aluminum frames, there are other advantages other then weight on a carbon frame.

    how did I bring the weight down to 25lbs you ask? Chris king hubs, no tube rims, Titec pluto saddle,crosmark tires, eggbeaters pedals ,race face seat post and stem, Martha breaks and new rotors.

    I give you an example of how I did so on an '07 Fisher Hi-Fi Pro. It weighed about 27 pounds even with SPD pedals when I got it (I'm not sure which version of the SPDs). It now weighs a hair under 25 pounds. The changes are the following:

    New wheels (Stans ZTR 355 with WTB hubs)
    Lighter tires and tubeless (Maxxis Crossmark Exceptions w/ Stan's tubeless set-up)
    Thompson Masterpiece seatpost
    WTB Rocket V saddle with Ti rails
    Bontrager Carbon X-Lite riser bar
    Avid Juicy Ultimate brakes (switched out from Juicy 7s)
    X-9 trigger shifters (switched out from Shimano LX tigger shifters)
    X-0 derailleur (switched out with the XTR so I could go up the upgraded shifters)
    Eggbeater SL pedals, but with Ti spindles

    I shaved 2.8 lbs changing:

    Cassette: Shimano XT 11-34.
    Chain: Shimano XT.
    Fork: Rock Shox Sid Team 100.
    Grips: Sette Superlight Foam.
    Handlebar: Specialized S-Works Carbon Flat.
    Rotors: Alligator Serrated Ti.
    Saddle: Sette SLX carbon/ti.
    Seat Clamp: Woodmand Ti.
    Spacers: Sette Carbon.
    Stem: FSA O/S 115.
    Tires: Continental Race King Supersonic 2.2
    Wheelset: American Classic Disc MTB 26.

    I'm also considering changing the seatpost and to convert it tubeless.

    I'm assuming that Fork swap was a big weight saver--is that right?

    gas money for epic trips.

    edit: just weighed an 09 Fuel EX 8 about 2 and a half hours ago in the shop. Full build + stock pedals (crank bro candys) was 29.4. Those pedals are heavy as fyck though, so I expect it is probably pretty similar w/out pedals

    Here's an ad from an eBay store that lists a medium frame weight at 5.84lbs.

    My 08 EX9 weighed 27.4 at two different LBS's. Different than stock is 2.1 crossmarks exception series tires, stans tubeless, specialized phenom saddle, easton monkey xc bars, pg990 sram rear cassette, bottle cage and candy SL pedals.

    Sure would like to get mine closer to the 25's. I guess wheels would make the bid difference.

    Nice build, but I can't help but wonder if you bought the wrong bike.

    Nothing wrong with making a trail-bike raceable, but the flipped stem, narrow bars, short fork (which significantly alters the geometry), all seem to contradict the original purpose of the frame.

    I have been running a F100RLC on my EX8 and the handling is good. It makes a more XC head angle (70.65*) and does not take away form the rear suspension working like it should. It does make the fork feel a bit short on travel; this is due to a bit of added front weight bias. I'll be going to a Float 140 RLC (HT will be slacked to 68.5*) this weekend so I will have a back to back comparison from short to longer. If I lived where the trails are not so rocky (Chico - Bidwell Park), I would stay with the 100mm.

    the handling is good, and confortable, and the fork size is 100mm. i think it dont afect the geometry, the ex 9 come with a talas and can be down to 100mm
