Would there be any issues using a 10 speed Crank set/chain rings in an 11 speed system? Specially a Shimano Ultegra 6700 (50-34) crank set with a 6800 shifter, 6800 deraileurs , 11 speed chain and 11 speed cassette?
I'm upgrading one of my bikes to Di2 and want to reuse the mechanical set to upgrade an older 10 speed bike. (I prefer not to change the front crank and chain rings if possible).
Thanks in advance for your input.
