    Sandman Gobi below 11KG



    Had a Sandman Atacama befor and used it for trail riding.

    https://picasaweb.google.com/1165786...9209/BeMC2012#

    But the Atacama was a bit to heavy

    Speclist:
    Frame : Sandman Gobi Aluminium
    Fork : Carver Obeast
    Hubs : 616 front and read 135/170
    Spokes : DT Swiss Silver Revolution
    Rim : Trialtech SL
    Shifters : XTR
    Front derailleur : XT with a problemsolver.
    Rear derailleur : XTR
    Stem : KCNC
    HandleBar : Extralite
    Seatpost : Easton Ec90
    Crank : E13
    Brakes : XTR
    Grips : Ergon

    As on the picture the bikeweight is 11,6kg.

    This is with:
    - a 12TPI Nate from around 1700gram (I'm waiting on my second HuDu)
    - 2 Heavy centerlock disk's (will be upgraded to XTR)
    - SLX Cassette and chain (will be upgrade to XT)
    - XTR Brakes (waiting for my Brake Force one's to come back)

    This all should drop the weight just below 11kg.
    How to land at about 10,8 (just below 24lbs) should be perfect for trail riding

    Getting the weight that low removes the weight objection to fatbikes.

    Neat build.

    Really sharp looking bike !
    And with some carbon bits and a set of tubeless Black Floyd's i think a sub 10kg bike is within your reach.

    This Sandman Gobi is great inspiration. When I get back from Oz, building a superlight fatbike is top of my agenda.

    Yesterday I remembered why a light bike is good. I scrambled 1,700 feet up a precipitous track with a bike on my shoulder. Luckily it was my fixie which weighs about 9kg. Nothing like the agony of portaging the Pugsley. A very light fatbike would suit the sort of riding I like to do because it usually involves some climbing as well as bogtrotting.

    insert jealousy here!

    i raced my Surly Necromancer at a cross race yesterday and it was extremely capable. Slower on the fireroads but made up for it in technical wet grass climbs and offcamber areas. ONE area it failed hugely on was the 20 step stair climb each lap (x8 laps or so). tried to run the first lap or 2....then ended up w a laboured walk holding the 36lb bike by the bar and downtube.
    i will have a lite front suspension fat bike for springtime :-)

    I have the same frame (aluminum Gobi), approximately 16" (size small). Weight of my frame was just under 4 lbs.

    its a Medium so it will be close to 18"not sure
    Weight naked frame : 1920 grams
    Not as light as a Salsa, but this is a 2011-2012 frame, don't know the weight of an 2013 model.

    You can shave off another 200+ gr by taking the paint off - would 10 kg be possible ?

    I've been counting, but below the magical of 10kg will be difficult,expensive and probably unusable.

    I can lose a few grams from several places.

    - tubes are DH tubes of 200 grams+100-150 gram latex in each. If I use the Michelin C4 I would drop about 300-400 grams. But I would risk a lot more flats
    - Paint as you mentioned 150-200 grams.
    - Rimstrip, replacing with ductape ore something
    - Lighter seatpost, Easton EC90 is not the lightest, a KCNC would be a cheap upgrade.
    - remove the ergon grips and use foam grips
    - Saevid saddle would lose some grams
    - Snowcat rims
    - I still use a problem solver and XT front derailleur, I have a E-type XTR but the cage is to short for using 20t in front, I find the combination of PS and XT stiffer as and XTR E-type.
    - Absolute black centerlock disks
    -...

    other options like a KCNC cassette from aluminium would not nice for the show, but not usable to ride with

    I'm looking forward to a new crank option which I can not tell to much about. You probably know where I'm talking about.
    But the project is not sure yet, I should have some more news next week (But he told me that already last month )
    That crank also should drop some weight.

    So Sub 10 is possible, but I do not have the budget for it.

    My Sandman Hoggar @12,8 kg (28,3 lbs), dirt included.





    The fork makes most of the difference, about 1,5 kg...

    There is not much more I can do at a reasonable cost (although HüDü:s were unreasonable). But it is on the other hand already almost 2 kg lighter than stock.

    Highlights:
    Tubeless HüDü ultralights, ghetto with light Schwalbe 20" tubes
    SRAM "XX" 9 speed cassette (second hand bargain)
    XT brakes, too good value to turn down, so powerful they allow 160 mm (Formula) discs
    Tune saddle (borrow from other bike)
    KCNC seatpost and stem (good value)
    Ti rear skewer for Trek ABP (my other bike) fits the wide hub!
    Front axle QRs replaced with bolts (front wheel removal is a pain anyway)

    I suppose the OP's Gobi must have a lot lighter wheels than stock, otherwise I can't see how it can be so light.

    If cost was no object I would build lighter wheels, but I think a set of 29er wheels will be more prioritized. It will never be really light so I will not spend a fortune trying.

    BTW I don't see any problem with the stock fd and a 20t cog. It will rattle if I go 20-11, but I don't intend to.

    SHi, Why did i get husker du's that fall right of the bead making it impossible to get them tubeless
    I tried getting them tubeless with 20" schwalbe tires and I blew the tire straight of the rim time and time again

    Tubeless would be THE upgrade on my sandman!!

    Yes so far, being a fat bike newbie, I found tubeless to be THE upgrade. Wire Larrys were super easy, folding HüDüs less so, but seem to work fine. Both need foam or something to fill the rim "channel" or they will not inflate.

    The only way I go them tubeless was with a tube as beadlock, worked fine untill I wanted to deflate,...

    You have the stock rims?

    Yes, stock Trailtech rims. I had no issues with the tyres blowing off. I actually took them up to 30 psi to set them on the rim properly. I'm still not sure I did, it's difficult to tell with the ghetto trimming in the way.

    A few more pics of the bike, still dirty.

    Are Sandman frames still made?

    Quite a bit of googling and searching mtbr has failed to find a dealer or a manufacturer's website.

    Can anyone help me out here?

    Sandman sells their bikes thru their own site and doesn't have any dealers (yet).
    It's more or less the same as with On-one.
    I hope this gives you enough info.

    Actually, they do have a few dealers in Belgium, Holland, Sweden, Finland and Japan... quite dispersed for the moment and all pretty recent. They're all "boutique" shops which have been willing to forego normal commission on new bikes because they really believe in the bikes. With production in a country like Belgium the bikes are not cheap (although the Hoggar is a great deal). Adding a normal dealer margin on top of that would send the price even higher, so dealers willing to (temporarily) cope with a lower margin than they'd have on another bike have been sparse. But those who have are now in the "front seat" with the 2013 Taiwan produced bikes.

    That model line is meant to be sold through dealers (and distributors for the bigger markets). Four models in total: the line starts off with a basic spec cromo, followed by a basic spec alu. Which shares the same frame with a higher spec all mountain/enduro. And finally a high-end ti. The last two models come with front suspension. The two basic spec bikes have rigid forks but the frames can accept to the new wide-crown Javelina suspension fork.
    Depending on dealer interest, all models can be sold as complete bikes, as rolling frames (frame, forks, wheels) or as loose frames.
    Eta: late winter.

    Last night on a tiny screen i thought it said :

    Why he's having a hard time finding the site, is beyond me though.

    I also was wondering why this was so hard to find….

    I never had a problem locating Sandman, drooling, placing my order receiving a sweet bike and riding the Sh*t out of it.

    BPRSNT,

    'Would love to hear more about your fat bikes.....is the sandman your race bike ? When do you ride the moonlander ? I don't have a fatbike yet, but several 29ers and almost always go back to my raciest 29er, so while the moonlander sounds like fun and is much more accessible, I believe a sandman would ultimately get a lot more use.

    I just ride for fun and have been using the Sandman as my all around everything off-road and it's been great!
    I preordered my Moonlander and bought it to ride in the snow last winter but ended up riding it all summer thru this fall and had a blast. I am keeping it and it will be my snow bike or when extra float is needed.
    If I had to pick one it would be the Sandman.

    Do you feel you miss the front suspension on the moonlander when you switch over from the sandman ?

    I do miss the suspension as well as the superior components and the geometry of the Sandman.
    That being said the Moonlander is still a great ride and half the price.

    I'm wondering/pondering the best process as well. Currently on a Necro Pugs w nates and ride it 100% of the time in dirt (no snow yet in atlantic canada...but fingers are seriously crossed). My 2011 XTR equipped Devinici moonracer is sitting doing NOTHING. Initially i was going to keep it and just sell my Necro in the spring to fund a high end (sub 30lb) fat bike w similar handling characteristics to the Surly but With front suspension.
    Now I'm convinced to sell both the pugs and the Devinci and fund a higher end fat ride that can handle full fat tires. Throw a set of Trailtech's and huskers for summer and a set of Rolling or clowns/Bud+Lous for the darker fun season.
    Current players for my money are Carver/Sandman/9zero7 and Salsa...whoever shows me best affordable front suspension and clearance for fat fat will get my hard earned cash very happily :-)

    In short i'm hoping for the yet to be released one bike to rule them all. The next few months will be exiting in this fat world.

    In order of questions : 170mm hubs fit all Sandman frames, yes, no VAT due for US orders, if you hurry they'll ship it for free - they've got a "free shipping worldwide" Xmas offer on Gobi's until the 15th.

    That was a question I had on 170mm hubs but I was also wondering who made them. I guess it is 616 and not 661. Considering that 661 is a huge company I think I would have chosen a different name. Lol

    Six 1 Six Fabrication is a small company in Michigan that makes hubs and frames. They named it after the area code for there location.
    I like there hubs. I am a fan of Shimano's Center Lock rotor attachment and presently they are the only one using it for Fat Bikes.
