Hi Guys

I am building a bike with Ultegra Di2 and want to use a new DA 9000 crank with 52/36 chainrings. Do you know if the DA 9000 cranks can be used with shimano 10 speed?


  • Disregard, just got this reply from Shimano.

    The new 9000 speed chainset is not compatible with existing 10 speed systems as the ramp and pin design on the chain rings as well as their spacing is very different.

    It is not much of a surprise they would say that but I would be surprised if they didn't work.
