Ultegra 6800 shifters with 10 speed cassette compatibility

[Dirtdiggler]

Hello all, first I apologize if this topic has been discussed before, I did google and search this forum.. So my question is.... Will Ultegra 6800 11 speed brifters work with a 6700 10 speed cassette, derailluer and crankset ?
Thanks

Nope. The cable pull is different. It wont match with the 10 speed cassette.
