    disc/disc rear hub for use with a tomicog or similar

    Does anything like that exist? That is, a rear hub with IS disc mounts on both sides to use as either a flip flop fixie hub or a fixed/disc hub.

    Not that I'm aware of. Closest thing would be a Phil Wood fixed disc hub (threaded fixed on one side, disc mount on the other).

    Yeah, thanks - I've got one on order. It'll probably get e-bayed though as I recently got a road frame that I can use for a fixed/disc bike with a white eno hub (original plan was to use an EBB frame instead).

    Why discs? For a cross bike?

    The only hub I've ever seen like that was on this 36er and it was custom.

    I remember seeing one on a tandem DH bike a couple years ago. Also custom, if I remember correctly.

    No good reason for it other than greed. It's a twisted desire to ride fixie without worrying about pedal strike, lack of braking but still have the advantage of virtually bombproof, simple components.

    Thanks - that's cool and obviously took some work to build. The toe overlap is insane - the pedals virtually rub the front tyre even before the wheel turns enough to hit toe.

    I don't think it would be fixed gear then. If the powercranks engage a sort of freewheel mechanism and you can't brake / slow down with back pressure you are riding single speed if I am not mistaken.

    Yeah, but, no, but yeah,...but if it's good enough to be used by ultra-distance fixie riders I thought I'd copy it with my own twists (disc brakes).

    That's cool but I still make the argument that if you put powercranks on a fixed gear bike it is not fixed anymore because it is no longer direct drive. Interesting concept though.

    it is on driveside but not on non-dirve, the "powercrank" effect is lost on the drive side. A waste of 8 hundo if you ask me

    Just so its out there ... Fitting a disc wheel to a track frame you can either use a 135mm rear hub for a fixed/free wheel and spread the rear triangle, or you can use a front hub with a 10mm spacer on each side. Probably cleaner if you aren't into that whole freewheel thing. I suppose you could use a disc rear hub with a Surly Fixxer and have a fixed/fixed wheel, but that sounds like an awful lot of money to spend.

    Just use the proper width hub for that monstrosity, and ignore the guy above telling you to squeeze a 135mm hub in a 120mm frame.

    Yes, I've done it. It works, and likely won't mess up a steel frame as much as many would like you to think. And it's still a stupid idea.

    ooooh, i know....

    Atomlab used to make a freewheel -> ISO disc mount adaptor. Basically, you spin it onto your freewheel threads and end up with a disc mount.
    Get a SS freewheel/disc hub and mount it.

    Though i have no idea where you can get on these days.

    what do you know - an e-bike store has threaded adapters --> iso disc

    http://www.ebikes.ca/store/



    I'd still prefer not to have to use freewheel/fixed gear threads. My two concerns are duranility of the threads and convenience of maintenance. Dual iso disc just seems like the better option.

    Now if only someone made it...

    edit: it's an old 135mm cyclocross frame with disc brake tabs just for your info.

    Disc brakes on bikes started life on threads with lock rings. That ended because they would strip, and weren't very durable. That is why we have centerlock and ISO.

    exactly - which goes back to my "jackass question of the month" - has anyone seen a double sided iso disc/iso disc 135mm hub that wasn't a custom job please?

    I sincerely doubt that anyone makes a 135 hub with disc mounts on both sides. You might find a 100m DH hub with two disc mounts, but that would probably be custom, super-expensive, or have a through axle.

    Dang. Had the same idea, went searching, found your thread. Shame nobody seems to make them. I wish thread-on cogs would go away, and switching to the ISO bolt pattern seems to be the best bet.

    same deal. i was looking for fixed/disc hubs, and found only phils, which cost more than the entire bike they'd be on.

    White also makes a fixed/disk ENO hub. I have one, and it has a Tomicog on the disk side. It is fantastic in every way. Not cheap though.
