Thanks for the Bikerumor link. This is very informative.

As far as our bike goes, it was a big upgrade from our 20 year old Co-Motion. We went with a Calfee Tetra with Ultegra Di2. Our old steel Co-Motion had bar-end shifters. I liked the bar end shifters pretty well. The Di2 shifts very well but I'm still having some issues getting used to it. If I am in the drops, it seems like a long reach to get to the shifters.

I don't have the bike here & I forget what bars are on it. The bike was assembled by a bike shop far away so I can't take it to them for custom fitting.

When I remember, I will take a photo of the bars & how they are set up.
