    My singlespeed Fatback!

    My sexy new Fatback frame showed up while I was away in Dallas but I got it assembled this afternoon enough for the maiden voyage in the melting snow around my house. I still need to finish up some things like getting proper zip ties, bleeding the rear brake and other "long ride ready" chores but it's looking pretty sweet! There will be some changes that affect the weight but it's 29.5 lbs right now rolling on 100's and it should stay pretty close to there after all is said and done.

    More pictures and info to come on my blog, including a step by step of how to winterize the bearings and such.

    Big thanks to Greg for helping me get one with sliders!

    Custom built with sliders. Damn spiffy.
    My video techniques can be found in this thread.

    that's REAL nice.
    I don't envy you pushing a singlespeed, but it's nice to have that option, especially if you throw some skinny wheels on there for summer duties

    edit: does that downtube 'twist'?

    Yup, that's the Helix downtube.

    No skinny wheels on this bad boy, I've got other bikes for that. As for SS, its served me well so far so we'll see how it does at the ITI

    Chris,

    Awesome ride. What kind of gearing does a guy run for something like Arrowhead/Iditasport?

    Currently geared 30x22 though I have several options to play with.

    That's an awesome build, I love it. What's with the hundies, though? Excessive, IMHO. J/K

    What other options do you have for gearing? Lower than 30:22? I ran 32:20 on my 29er for crust riding and blown-out, late-season snowmobile trails last year and it was very usable. If you're committed to SS I'm sure you can find a comfortable racing gear. Snow is pretty changeable, but riding technique can overcome a lot of difficult conditions.

    Nice frame, but I can't take my eyes of the wheels. Maybe it's just that I've been off my snowbike with 80's for a couple rides, but the Endo's on 100's look ginormous.

    Easier and harder gearing options but I'd be shocked if I changed more than a few rear teeth either way (20 to 25 rear). I've got a pretty good handle on what my body wants. Maybe snow will complicate that but I guess that's the fun of trying.

    The 100s are excessive. If I wasn't going to McGrath this year and Nome in the future I would be rocking the Uma IIs. But riding is better than pushing, hence the 100s. I want to track down a Larry for the front. I've used the Endo's quite a bit and the Larry "looks" better.

    Glad to see the bike arrived, though it's ironic that you got it built when the temp got into the high 50s. Hopefully things will freeze up again and you'll get to play in the snow.

    The big question is how does it wheelie?

    Haha true. Luckily the high pressure should set up the high country riding nicely.

    It wheelies pretty good. I'll try to get some shots when I'm done working on it today.

    Yep I'll be at the AH. Any CO people are welcome to come check it out and ride it anytime as well.

    I'll have to take an end of the day picture and reweigh it later. Busy working all morning after getting back from the Depot. Oh the new stem and a Larry are in the mail as well!

    Nice build .

    i can't belive it weighs that much as a single speed. i'm at 29.5 and akgreeff is under 29 w/fully geared bikes. but we have drilled 80's.

    Must be all in the wheels eh? it's crazy that they make such a huge difference. A good consideration for people trying to decide b/w 80 and 100mm rims.

    Waiting on my Epic bags for winter to arrive CRC.

    Weight...yes it's a bit porky right now. 100's are 1530g each rim undrilled. A few other things are heavier than they will be for the final build. My guess right now is I'll end up at 28lbs or so after doing a little rough math this morning but we'll see. In the end if the 100s keep me riding, they're worth the weight.

    EDIT: And it's still lighter than my Pugs was!

    Can you post a close up shot of the sliders on the rear end? I have a crazy idea of a Rohloff Fatback and I guess it would use the same rear drop outs.

    Do you know your chain line in millimeters?

    Rohloff Fatback would be sweet, but with a 135mm hub and a 165mm frame, would you get the frame custom made to 135 offset, or even non offset if it is IG/SS specific, or extend the Rohloff axle somehow and respace it on an extra long axle to the right chainline?

    I think the chainline is 65mm? It's the middle ring spot on a Whirly with a 100mm BB shell. I'll have to resize the pic of the sliders, it's too large for MTBR.

    That thing looks great Chris, very nice! Weight is pretty good considering the 100mm rims. I have a Fatback aluminum on the way, can't wait to check it out.
    Good luck at the races.
    Guess it's been a while since I read your blog, wow! Glad to hear the ankle is healing up well.

    I think the snow might complicate things. FWIW, I thought it would be nice to go single, but I setup my fatback as a 1x9. Logging some miles in a range of snow conditions forced me to go 2x9. I can't imagine getting away with a SS given how much difference the snow conditions make.

    Singleshizzle getting all packed up in the car for AH. Looks sort of like this naked and this with bags on. I rode in some pretty marginal stuff and the 30x22 is not a half bad enduro snow gearing.

    Yeah hot for sure.

    That's my winter set up fetish.

    Does it handle BFL's is the next question. Sorry I have to ask.

    Since Rohloff and Fatback are mentioned here, I have to ask: Does anyone know if Greg/Speedway have plans to design a Rohloff-compatible Fatback?

    Although Rohloff was not specified, Greg mentioned an IGH adapter as being in the works early into the illustrious (and lengthy) 2012 Fatback thread.
