    On One Fat Bike Frame

    Brant Richards is back at On One and today he posted these images to his blog: » It was like that when I got here #oosnowbike Shed Fire : Designing for On-One, Titus and Planet X from Calderdale.

    Obviously not Brant's design, but we'll see what becomes of it.

    Aluminum, yes.

    Can't really see them, but it hints at having the swap outs. This would allow someone to get a single speed set up, and then trade out the drop outs for a geared set up when wanted.

    Obviously we'll have to wait for more details, but I like the styling, and frame bags should work well with this.

    I have a 1.5" head tube on my diy frame, and a Cane Creek ZS44 headset was relatively cheap, and works okay. Very future proof, you could run forks with tapered steer tubes.

    It's Shiggy's design. There are two of them. Headtube is 44mm. Doesn't really need to be, but hey, why not, it fits the downtube nicely and maybe we can make some mad singlesided fork like I keep wanting to make. Long way to go yet.

    ps: I did Iditabike in '96 (14th) and '97(6th), but did it on Snowcats and Conti 2.2in tyres.

    The top tube / chain stay thing suggests vertical compliance but how does that match with using aluminum?

    Twin top tubes make me worry about the width and hitting my knees on them. I've never ridden a bike with twin top tubes, so my worry could be totally groundless.

    No.

    Infact Shiggy wants to deflect the issue that we're "late" for this year (but in time for next) by calling it a "Rock Crawler". I wonder what a bike with a slack head angle and a 6in suspension fork would be like with a 4in rear tyre (I'd just take off, right?).

    Lots of fun, no doubt.

    Can you tell us what axle to crown length it is designed off of?

    This frame may have just answer a lot of debate for me!

    Currently is 470mm a/c with a 71deg head angle. This may change. I certainly want to mess around with head angles a bit.

    Oh sweet, I was so hoping my Enabler fork would work well with it.

    Now please tell me it's a symmetrical design?????

    Any hints to chainstay length?

    About the only thing different I'd want on that is an EBB, and that's simply because it allows you to make adjustments to the chainline at the front.

    Symmetrical, 170mm (it says on the drawing), 445mm chainstays.

    But it's just these two first samples. Anything could change. And might/probably will.

    A slacker head angle please, more like 68. The fork can be 2-3" of travel. Maybe a soft tail?

    As long as there isn't any huge changes, I just found my next project! This is exactly what I was looking for and has just saved me a lot of time debating some things, thanks guys!!

    I'd be in favor of a slacker HT angle too.

    3 Q`s......

    1) What is the rear tyre clearance ??

    2) How about calling the UK version the "Dune Surfer" in honor of CK or the "Bog Monster" , in honor of Velobike's exploits in trying to ride through proto Lochs

    3) If you do a `mad` one sided fork , please ensure that it IS really mad with ( dare we say) adjustable clamps to allow better tyre clearance and adjustable A to C

    WOW! Sure love the look of this one! Kind of has a trials bike look to it aye? Not sure about 71 degrees at the head tube... might be a little steep for snow & sand... nice to be a little slacker on a downhill when the Ft. tire sinks into soft snow or sand... of corse we don't know the effective TT length yet either. LOVE the double TT w/ super low stand over!

    I'm not so sure about a slack head tube angle. I have 69 degrees on my frame and it feels a bit floppy at slow speed.

    I like it! And as fellow members of the Commonwealth please ship some to Canada! The American manufacturers aren't really interested in selling us their bikes, for whatever reason, at least not without gouging us, and we have 35 million people and a very snowy country just waiting for some snow bikes.

    Well, I know Shiggy had me measure my Rolling Darryl/Larry tires and I gave him that measurement to go by several months ago now. Hopefully he "future proofed" it a little bit.

    I like the appearance of the toptube....but what I like even more than that is the possibility of greater framebag volume due to the wider "toptube".

    Is it me or is that seat-tube curved or bent, a bit like a Surly Karate Monkey?

    I see that as well. An attempt at shorter chain stays, I presume.

    EDIT: I see further up now where Brant said the chain stays are 445mm/17.52". Not all that short after all! But then again, for soft stuff, short stays seem to not be wanted.

    I like Shiggy's suggestion that this is a "Rock Crawler", by the way.

    Nice looking frame!!

    I think the oversize headtube will allow a lot of room for people to play with the angleset headset. It is nice to have the option of slackening the HT out or gettting that perfect geometry out of a production bike. It might also be good to change the HT angle for different types of terrain or seasons.

    Very good point, if they went say 70 degree HT angle then we could all tweak it to where we really want it.

    This is pleasing for those of us that will be using it as a "Rock Crawler" trail machine instead of a sand/snow bike.

    Brant,

    I know this is a wee while off, but does that mean that planet x/on one will be taking in stock of fatbike essentials - tyres, rims, bb, forks etc?. Excellent news, nice to see some more fatbike development in the wings...

    BTW, just built up my Mk1 bluepig, lovely frame
