Here's my ride, a 2015 Trek Domane 6.2 Project 1 with the Ultegra Di2 after a ride west out of Gainesville, FL into Trenton.
I'll turn 59 in December, just under 5-11", and ride a 58 cm. The bike fits me like a glove.
I'm actually thinking of turning it around and getting the 2017 Trek Domane SLR 7 (ridden, awesome!) or the 2017 Roubaix Pro (pics only, need to try it!).
Both have the Di2 (completely sold on electric shift).
Life is good..................
