Quick 10/11 speed question

Hi, I was wondering if I can use a Shimano 11 speed crank with 10-speed everything else. Thanks!

Including chainrings?

Yes you can.

Including chainrings?

Yes, with chainrings. I realize I may need to run an 11 speed chain.

I figured the answer is “yes” since the 5-piece upgrade kits don’t include a crankset.

The older 10-speed chainrings (Ultegra 6700 or Dura-Ace 7900) won’t work with 11-speed cranks. Shimano moved to a X four bolt pattern with the new 11-speed stuff. The older chainrings are the star 5 bolt pattern. So you would need to use the new chainrings.

Cool. Very helpful. I’m building a new bike, and have tons of 10-speed stuff except a crank. I may as well invest in the 11 speed one (with chainrings). Thanks.
