Can I swap crank arms between groupsets?

Hi

I have a Stages PM on an Ultegra 6800 crank arm, currently looking at TT bikes. Forgetting the looks for a minute will I be able to use this on a Dura Ace 9000 or 105 5800?

Cheers

    Assuming it's on the l/h side (non-drive) then yes as they should be the same fixing. The chainring side prob has 130 or 110 bcd depending on what size rings you use. Happy for someone to tell me that DA uses a special Unobtainium fixing bolt

    11speed (5800, 6800, 9000) actually has a 4 ring bolt (not sure BCD) and all chainring sizes fit to it (compact and standard)

    Interesting question though. Try 'training' or amateur race.

    I think they're all HollowtechII fittings - so you can fit that Stages PM to any of the cranks.

    I know I can put my Stages105 pm to my Ultegra 6700 crank or 105 5700 one.

    The BCD doesn't matter as it's non drive side.

    Assuming the crank arm is the same length the yes. I currently have a DA9000 stages on an Ultegra 6700 chainset (Winter hack)
