    2013 Frame Weights and IGH Compatibility

    Frame weights?

    Twenty2 Cycles TI (M): 1605g
    Beargrease (M): 1660g
    Fatback (M): 1786g
    9:ZERO:7 (M): 1900g
    Sandman Gobi (M): 1920g
    Mukluk Ti (XS/S): 1940g (M): 1968g (L): 2048g (XL): 2108g
    Mukluk (M): 2200g (L): 2320g
    Moonlander (M): 2550g
    Pugsley (M): 2570g

    Fork weights?

    Carver O-Beast Carbon: 578g
    Beargrease: 720g
    Carbon Fatback: 820g
    White Brothers Snowpack: 910g
    9:ZERO:7: 1040g
    Moonlander: 1138g
    Pugsley: 1140g
    Enabler: 1176g


    I see that both Fatback and 907 have new frames to accommodative IGH, belt drives etc. I assume that means I wouldn't need to run a chain tensioner with an IGH on either?


    What about the Beargrease can I run adapters on that to fit an IGH? Assuming a chain tensioner is required here.

    Besides the dropouts were there any other changes to the FB/907 2013 frames, geometry wise?

    No

    No Geo changes on either AK bike from what I have seen. Gonna have to wait for frames to be completed for weight answers.

    Great thanks, used the Fatbackbikes listed weight for the Carbon Fatback Fork (820g)

    Just need a weight for the 907!

    Also can anyone shed some light on the IGH compatibility of the different frames?

    Does the O'beast fork work on the Beargrease frame? Any recommended headsets?

    The Large 22 above is for a rohloff ti frame with rocker dropouts. A standard model hits the scales at 3.54 lbs.

    So 1605g for a Twenty2 Cycles TI (M)? Or when you say standard do you mean not TI?

    Okay. Noob answered his own question. Beargrease comes with aluminum fork.

    Next noob question. Can I use my unused ISIIS 50/.34 FSA Gossamer crankset? Treefrort bikes has the frameset and says this:
    The Beargrease uses a 100mm bottom bracket shell. This means your standard outboard bearing mountain crankset will not fit. If you have an older ISIS crankset it will fit if you use a DH bottom bracket such as the one offered by FSA. E.13 and Surly offer fat bike specific cranks that work well and will give you the greatest gear range and the least amount of chain rub.
    Can anyone recommend a bottom bracket?

    I was speaking to the 907 folks recently and they expressed a strong preference to head in the 170mm width direction with their frames. I'm not sure what that means for the availability of the 135mm frames with sliders, but if that's of interest to you I would confirm directly with 907 that you can get one in the size you need.
    Safe riding,

    Rohloff and 170mm... can it work?

    I'll preface this by saying that I've not (yet) tried it and that no one should take this as advice or fact...

    But on speaking to a dealer of mine that specialises in Rohloff conversions, who has just built a 170mm spaced frame for a customer... (he's also a framebuilder)

    they see no reason why the Salsa offset adaptor (Salsa Cycles | Components)
    could not be used with a QR axle Rohloff, a Salsa 170mm skewer and a Rohloff Monkey Bone adapter to the disc mount bracket.

    "in theory"...

    Any input from the assembled MTBR masses? Anyone tried this?

    I own 2 Rohloffs. If I am going to install a $1600 IGH on a bike I'm not going to hack it to make it work given there are frames that exist that work off the shelf and that a custom frame is an option as well.

    I agree, if you have the means to buy it, don't piece it together. Also, not all belt capable 135 frames meet the requirements established by rohloff for use with the gates system..When we started testing frames in july gates had to make an adapter for the 100mm bb to test them so we know that no one else had tested any at that point.

    The new sliding dropout frames due in next month have 135mm dropouts so I have contacted them about a pre order seemed like the best frame for the job as a lot are moving to 170mm (salsa, fatback etc) and would require adapters and a chain tensioner (for alpine removal) I'm pretty sure I can do away with both on the new 907 frame

    Imma stop drinkin' beer and posting to discussion forums now. I've only ever built a road bike and I was so freakin' excited that I might be able to afford a Beargrease frame ('cause I have a crank already) that I forgot MTBs use much smaller chainrings than road bikes. Even compact crank road bikes.

    Well, If I use my 50/34 ISIS crank on a Beargrease frame, I'll have the fastest fatbike on the road, by golly. God willing, I might even be able to climb a hill.

    Curious if anyone knows if a Beargrease fork would work with a fatback frame?
