    Arctic Fatty Build (9:ZERO:7)

    Thread for the build for my fatbike/packrafting expedition to the Arctic Ocean.

    I'll update as the build progresses. A few key bits:
    • 9:ZERO:7 135mm offset
    • Rohloff
    • Schmidt SON28
    • Large Marge XC


    Frame choice in a nutshell: Rohloff and dynohub are required to accomplish the goals of the expedition. The Rohloff Speedhubs are only available in 135mm and the Schmidt hubs are only available in 100mm. I prefer the offset build to the various 170mm rear end options requiring adapters/spacers. I also love the standover height of the 9:ZERO:7 aluminum frames.

    Oh, and... after living on a sailboat with a bike for about 3 years, I've experienced the accelerated rates of steel oxidization in marine environments firsthand. I'm disqualifying the Pugs and other steel frames for that reason.

    Just snatched Step 1 off the truck...

    I'm really stoked to see how this progresses. The electrogenerator front hub, non offset, Rohloff rear end.. this oughta be super cool.

    Just curious what your timeline is for this trip, ie. when you are planning on being where, that sort of thing.

    Interesting trip. if no liquid or gas fuel for cooking your fuel plan for heating water/ food? I can't imagine the trip w/o hot beverages and only raw foods

    you forgot, no wood either - from the website " a world in which humans are freed from the reliance on burning dead stuff for energy"

    While these questions may all be interesting, I'll primarily be discussing the build in the context of mtbr sub-forum fat bikes.

    No hot drinks or cooked meals in between villages shouldn't be that much of a problem. I always had foods I didn't need to cook and water with or without drink mixes on my tours.

    From the website:


    In the last week of March 2012, I'm heading north to the Arctic Ocean on foot, fatbike, and packraft. The estimated duration of the expedition is 6-8 months, but may vary significantly due to ice, ocean, and ground conditions throughout.

    I'm with ya... was mainly dodging the food questions. As far as the bike use (very oversimplified), Spring will be road, gravel, ice/snow trails, and maybe frozen rivers/lakes (route has alternate options based on breakup). Summer will be tundra. Fall will be bushwacking in the southern half of Alaska and the Lost Coast.

    The OP is using access to his travel techniques as part of his revenue stream, hence a reluctance to share information here for free.

    That has absolutely nothing to do with it.

    still waiting on crucial parts, but here's a (grainy) quickie...

    Those dump bears are like our menacing pets. Something about those bears on the other side of the bay, they have a grumpiness about them.

    braze-ons off / plasti-dip

    oopsies... the braze-ons fell off. removing them might seem superfluous, but every little bit of metal sticking out is a potential problem when the bike is strapped to the packraft.

    i left the appropriate cable-routing braze-ons and a few rack mounts to potentially stabilize heavyish bags.

    removed: lower rear rack mount, rear derailleur cable guides. front derailleur cable guides/stop, canti brake bosses.

    stage 1 of plast-dip. it's kind of a pain to work with. regular masking doesn't work; all masked lines must be pulled immediately when still wet. this causes problems because it forces you to do one thick coat along the masked edges. other than loving the matte finish and rubberized feel, it's probably the wrong choice for this project.

    the blue masking tape is just for coverage between the cleaner edges, which are electrical tape. the black seen poking out at the edge of the logos is the electrical tape over the logos. it's way easier to mask curves with the electrical.

    This looks interesting! I have thought about plasti-dipping bike stuff before but never had the balls to do it! Can't wait to see it finished!

    The cool thing about Plasti Dip is that if you mess up, you can just peel it off and try again (as long as we're talking about non-porous surfaces). This will be the second frame/fork I've done. It went okay the first time, but I'm definitely tweaking some things.

    Cool, How many cans does it take to do a frame and fork?

    2-3. I'll probably use 3 this time... seems like messing around with the masking process results in more overspray/waste. I think I used 3 last time... didn't mask off logos on that bike, but also did bar, stem, and cranks.

    Oh, this time will be 4 sorta. I'm going to use flat clear over the logos to cut down on its opportunity to peel at the edges. But... that will just take a fraction of a can.
