I did it. Went with the 2016 Domane 5.2. Looking at the photos online of the white/silver, I didn't think I'd love it. It was "okay."
I'm surprised at how much I like it now that I have it. It's beautiful. Very sharp. Striking. It's an eye-catching bike.
Absolutely love the ride. Smooth, comfortable, but fast. Responsive. Great climber. Feels light underneath me. It is quite striking how little road noise I feel. It feels like I'm riding on air.
Bottom line: I'm thrilled. I likely will have this bike for a long time.
Thanks all, for helping me make up my mind.
