    This looks good - 650B (Reynolds 853) Hardtail

    Not a dedicated 650B frame but clearance for 2.5 tyres and sliding dropouts ... Plus 853 main frame!

    Pipedream Sirius R853

    I reckon this would build up nice... Designed to accept 100-140mm forks I think(?) so i reckon it'd be happy with a 650B/120mm front.

    Give it a go!

    I'd like to see someone throw some 650bs on the Orange P7 frame with a 120 or 140mm fork up front to see how that'd look and ride. The sale price at www.unrealcycles is a really good one on those frames right now too (the 09s)

    I posted about this awhile ago but the Transition Bank will clear a NeoMoto. It uses a rotating axle mount which looks a lot more secure and cleaner than sliding dropouts do.

    http://www.transitionbikes.com/Bikes_Bank.cfm

    $555 cdn for the frames, compatible with 130 to 160 single crown forks, 4.5 pound frame weight, ISGC mount, 135mm thru-axle, 1-year defect warrant / lifetime crash replacement.

    I love the look of transition stuff but the bank is surely a jump bike ... I don't think 26" wheels even belong on a jump bike.. nvm 650B

    However the transition Trans Am looks awesome ... although i don't think it would handle 650B and it does weigh a bit !

    The Bank is intended as a jump/4x course bike yes. But at 4.5 pounds, and that geometry with a long travel fork... I'd run the thing on north shore type technical singletrack with 650Bs. I'd need to run a monster of a seatpost though... 13.25" seattube just isn't enough for someone 6'6" to actually be pedalling while seated. The large size's 24" toptube is nice though.

    reply from pipedream

    just got this back via eMail:

    We are getting asked that question more and more thesedays. Even
    though the frame is not designed with a 650B wheel in mind, we have
    calculated that the a wheel of that size will fit.

    A pair of 650B wheels and tires are being made up for us as we speak,
    so if you can bear with me a few days we will get back to you with
    some photographic evidence.

    If you are in a hurry for your frame, you might also consider the Ti
    version of the Sirius. Because this frame is made to order, we will be
    able to change the design (slightly) so that a 650B wheel with a 2.3"
    tyre will definitely fit.


    i guess that means wait for the photos ...

    my sirius r853 frame arrived just before i took off for a week in the alps - anyway, i can confirm that a neo-moto 2,35" fits with oddles of space and i can even push the sliding dropouts 5mm forwards without danger of rubbing the stays ...

    i guess i'll be buliding it up over the next 2 weeks or so, pix sometime then if anyone's interested ...

    So how's it coming along? This frame definitely makes the short list. Please post pics if you can. Thanks!

    parts have been ordered and i pick up the prepped frame tomorrow - i'll post pix soon ...

    workmanship on the frame is good, certainly can't fault it anywhere there. the paint looks like it could be better, but what should one expect for the price? ... if it proves to be a problem, i'll just get it powdered ...

    if it's just the rear tyre clearance you're worried about, then don't be - there is more than enough space everywhere, even around the neo-moto 2.35"...

    With the 2.35 mounted, where are the sliders located? back, middle, front? Thanks.

    see post #9 ... 5mm back out of 17mm total adjustment, and still not too close to anything ...

    somebody wanted to see pix of the pipedream sirius 853 rear end with a 650b set-up ...

    the tyre is the 2.3" pacenti neo-moto on the latest velocity blunt rim (not the P35). as you can see in the pix, there is plenty of room (those are mm graduations on the ruler), and this is even with the sliding dropouts still around 5mm from the endstop ...

    the build is not finished yet (obviously) ...

    it's only the standard (battleship) light grey ...

    i guess the camera makes it look a little violet, but it's not.
