I just bought a new BMC GF02...Ultegra mechanical. Coming from a few year old mixed group Synapse I'd got it in my head that I really kinda wanted Di2. If I had ordered it out that's what I would have purchased. But I ran into a good deal on an in-stock left over 2015 mechanical. Rode it for a dozen test miles, liked it (including the color), and figured what the hell it's upgradeable If I want. Pushing 100 miles now, I'm glad I went with it. I don't find myself shifting as much and, with the 11-32, am so far spending most all my time in the big chain ring. Front der shifting with my old set-up was what was driving me toward Di2 in the first place and that on this bike is also much better. I'm a rec/fitness rider these, tho, so YMMV.
