Upgrade to 11 speed Shimano
I would like to upgrade my bike from the 5700 Shimano 105 group set (10 speed) to 11 speed. The crankset is the Ultegra FC-6800 compact crankset. Can I simply get a 5800 or R7000 11 speed shifter, 11-34 cassette, and 11 speed 105 derailleur? To give you an idea of my riding, last year I climbed 207,000 ft.
