I will never go back to a Shimano mechanical group. My 2012 Force 2 X 10 has been more reliable and easier to keep in tune than my Ultegra group was, and Doubletap shifters are so much better IMO. Firm brake levers, not the mushy side-to side floppiness of Shimano.

Regarding the pro peloton, aren't 99% on electronic groupsets nowadays? Kind of eliminates SRAM rom the running, at least until this year when SRAM got the wireless groupset up. Will be interesting see the next evolution of eectronics, do you think everyone will go wireless?
