Purchased this group from Downers Grove Trek (concept store). DG trek did the install and although I've only riden twice for total of 65 miles this group is what I've been looking for. Spot on shifting, got to love the pop sound it makes when shifting. Crank is extremely stiff,brakes are superb,and as good as rear derailleur shifts front shifting is the best I've ever had from any other group that includes SRAM red which I've owned and campy super record which I've logged apprx 300 miles with. I'm not hating on SRAM and Campy cause there obviously 2 of the top 3 groups in the pro peloton but for me and once again group is very new but it's just so accurate and simple takes no time at all to get comfortable with unlike SRAM and the thumb thing with Campy never got comfortable with it. And that's what is so amazing about this group being so new and just so accurate no phantom shifting no in-between shifts it's like completely broken in from mile one. [...]
