    My buddy traded some wheels with me from his demo 8. Mine were lighter but still pretty stout.....32 spokes instead of 36 and a hugi hub instead of the specialized stout hubs.

    He has dh minions on there as well and his bike is 40lbs.

    Hey what kind of shocks have you guys been using? The Manitou is really plush, but I hear they blow out quick, and I kinda want a back up. Thanks!

    i don't really like my manitou. I think its the spv. i run it at 50 psi 24/7 because i just hate the platform. I plan on changing it out for a dhx this winter. its all about the preference though.

    One of the guys over on MTBR claims that he has it down to around 38.5...DHX, TI spring and tubeless. Pretty nice weight for a race bike.

    Especially for such a burly, stiff race bike.

    No doubt...light, still and can take some pretty serious abuse. I'm still suprised that they don't have a thru axle option at least for the D8 though.

    E-speculation: with the uber short chainstays of the D8, a thru axle wouldn't make a noticeable difference. The D8 is really stiff as it is, even on a high speed run, like the Snowmass DH course, I couldn't feel any real flex. I'll bet putting a true thru axle on it would break things pretty fast. Too much stiffness in one area will just transfer the force onto something else. Then that other thing breaks. Like a chainstay, or a weld. The D9 has the through axle and it's a lot beefier. The D8 comes with a bolt on rear wheel though, which is kinda like a thru axle. Damn, I wish that bolt on was a quick release. After riding Whistler for a week with a quick release XT hub with a new X321 rim, I had zero probs. Quick release=happy. No hoping that someone has a Crescent or 15mm wrench when you forget yours...

    well considering the person who gave that information is the guy specing the parts that went on it, I'm inclined to believe him. His personal Demo 8 last year was at 37lbs.

    I would like a thru axle because of the security, more than the stiffness. Yes it is a pain in the arse to take off, but I'm not 100% confident in qr wheels. I've had a qr wheel slip out before on a dh run and it sucked. The thru axle would prevent that. Just imagine hucking way up just to have the wheel slip out...not a pretty sight.

    You don't need to run a QR you can still run an axel and bolt on.

    imagine doing a 60 foot step down gap jump while pulling a Suicide No Hander? Oh wait...Strait did it on that bike and has been clocking World Cup Top 20's on it too.
    Our team ran DHR's with QR in '02 and never an issue.

    that will be sick then if it is 40.5 for a stock bike, the qr is sick for that bike it is so stiff, I go a 10mill conversion kit for my dt 240s hub to run a a 10 mill bolt on axle to make it stiffer and stronger since I was running a crosscountry axle that wasn't to strong for dh.

    37 lbs. for a Demo 8???

    What is the spec sheet for that build????

    I've got a 888RC on mine right now, and with tubeless plus a DHX w/ Ti coil, and Middleburns, I've calculated something in the neighborhood of 42.22 lbs.

    If I had an 05' Boxxer WC on it - that would shave .5 lbs. off of it... but 37!?!... Wow. Maybe my scale is off. Hmmmmm...

    Actually I too am going with a T/A for next year. My current rear hub is a DT Hugi FR, with a Hope Steel skewer, but I just like the idea of a solid axle in there. Probably gonna get a Hadley w/ the regular 36pt. engagement...

    Question though:
    For T/A's (Through Axle) does anyone know if you can get washers that have one knurled side like the compression washers on QR skewers???

    "Hey Early, how big was that fish ya caught last Thursdee down at the hole?"
    "Oh, I recken about 27 inches, four pounds or so."
    "Huh, coulda sworn it was about 24 inches, three pounds."

    I'm riding the fork it came with (05 Boxxer Ride) right now and I'm going to upgrade to a Fox 40RC2 soon. I don't really like the boxxer's stiction right now, and it's John's bike, so you know the fork is broken in. :D

    Well they were lighter than the old ones, but the new WC is way lighter.

    not 30k, zed, 5K ;)

    Demo 8 II is listed as $4900:
    # Externally adjustable Fox 40 RC2 fork, 200mm travel, external rebound, hi/low speed compression adjustment, 20mm thru axle
    # Lighter Avid Juicy 7, hydraulic disc brakes with 8" Polygon rotors
    # Lighter SRAM X.0 carbon, micro cage rear derailleur and SRAM X-9 Trigger shifter
    # Lighter Truvativ Howitzer Team crankset
    # Stronger Mavic EX721, 26", 36 hole

    ....or save your pennies for the mere $2800 for the frame!

    I'm just hoping under 43 for my build.

    boxxer team
    DT rims
    DT double butted spokes
    profile cranks with ti spindle
    ea70 bar
    sic intergrated stem
    kenda tires
    shimano xt rear hub
    e-13 lg1 guide

    PS I know i can make it light but parts were selected based on manything weight was one of the last factors.

    05 Demo 8 - 41.5lbs exact

    888
    SPV 4 way with ti spring
    EX823 (05 rims)
    Middleburn cranks
    Avid J7
    Gamut guide
    Spec Pro tires 2.4"
    With Maxxis tyres it would be 42.5lb

    40lb would be possible say with a new 06 Boxxer and a different rear shock but I think under 40 would be stretching it.

    i would try dripping a few drops of tri-flow on your seals and maybe even upgrading to some spectro gold or other misc. high grade MX fork oil. half the boxxer bashing wouldn't exist if everyone would do this. i do it b4 every ride but you could probably get away with it every 2 or 3 hard rides.
