Is the left (non drive side) Ultegra 6700/6750 crank arm compatible with the new 11 speed 6800 crankset?

    why not just leave the crank as it is? makes absolutely no difference to the rest of the groupset less moving to a triple or vv. you could fit 11 speed everything else and keep the same crank on.

    TBH I would be surprised if it has even changed in design from 10 to 11 speed.
  • I am about to buy a bike with 11 speed Ultegra (6800) and want to know if I'll be able to use the (6700/6750) crank arm with stages power meter attached from another bike (winter trainer/turbo). Can't afford one on each bike!
