    Thoughts on the new DUB cranks?
    As a guy with multiple bikes with bb92, bb30, s24mm and 30mm spindles, a x01 crank, and a race face next sl g4 crank... i was initially impressed that sram was making a system to increase crank compatability... not add to complexity.

    The raceface cinch system sold me because it allowed me to invest in a very nice set of cranks, and by only changing spindle length, and possibly getting a new bb, swap my nice cranks from bike to bike.

    I was disappointed that the dub does not have removable cranks... so you are stuck with chosing one spindle length. No swapping your xx1 crank from boost to fatty spacing for example.

    So although i applaud their overall product, it is frusterating to see yet another spindle standard at 28.99mm...

    i guess it is all just business warefare. They want to stay a step ahead of the aftermarket guys. It will be interesting to so how companies like raceface respond...

    I also know that the raceface spindle mates with the old sram cranks (if you punch out the old spindle), and i bet that compatability will be lost. Haha.

    Honestly, while I do really like SRAM stuff, I'm not impressed or enthused on yet another variation. When your "new standard" is passe' faster than your iPhone, it's a rather disgusting feeling. The notion of "standard" is now simply an excuse for "proprietary marketing". My current bike is a PF30 and my next bike will be either that or a threaded 24mm.

    Yup, for sure.

    My issue is that new bikes will come spec’ed... and then the game continues. It is a money thing. Big business in bikes.

    I just built up three bikes with SRAM Eagle drivetrains - including GXP cranksets. I'm not excited about having to replace my bulletproof Hope bottom brackets with DUB ones should something go pear-shaped with my cranks. Oh well -- it's probably only a matter of time before Hope comes out with a DUB-compatible BB. I just think SRAM is solving a problem that doesn't really exist and, despite the marketing hype, the real motivation for them was to reduce the number of crankset SKUs they'll need to offer.

    In the end it's not that big of a deal but I don't think the world was really clamoring for yet another BB standard. Between GXP and BB30/PF30 there are already enough BB configurations available to fit basically every frame out there.

    For SRAM...by going with one spindle size...it'll cut down production costs. Currently they have the GXP and two different lengths in the 30mm spindle.

    Shimano only makes one spindle size.

    I'm running GXP cranks on my bikes...and I don't plan on switching them out any time soon. GXP BB's will be available for quite some time.

    The DUB cranks have no affect on me.

    SRAM's eagle is taking over the drivetrains on most new bikes. Those new bikes all come with DUB BBs. Seems to me they are leveraging their advantage with eagle to make dub the new standard.

    Can someone tell me what BBs are compatible with the xx1 dub cranks?

    One thing to keep in mind, the crank installation bolt you need to tighten to 54Nm has 'black threadlocker' applied out of the box. It seems to lock the bolt real tight overtime, making it near impossible to release. There are tons of threads on this issue already. If you install the crank and loosen it again straight away, the threadlocker peels off a little and you can remove a big deal of it with a toothpick.
