Shimano 105.. ST-5600 brifter compatibility w/ DA & Ultegra
I just got a pair of ST-5600 shifter/ brakes on CL. My existing set up is Shimano Ultegra double crank up front with Dura Ace FD-7403. Rear is Ultegra RD-6500 and 9 speed Sram cassette with Shimano 9 speed bar end shifters.
It all works great and I set it up myself from scratch.
Will the 5600 brifters work with my existing hardware and if so do I need to do anything special since it's a 10 speed shifter w/ 9 speed gears?
Thanks and I couldn't find this exact question answered. Sorry.
