Ultegra 10 and 11 speed cranks....?

Basically what is the difference and will a 6700 chainset work with 11 speed

Yes - one's 4 arm (6800) and the other 5 (6700) but they'll work fine. My youngest's running an Ultegra 6800 crankset on his 10-speed Campag Record set-up as we couldn't find a Campag crank short enough for him.

For info I'm running a 6800 crankset with 52/36 rings on a Sora system that's currently 9 speed.
