I went to my LBS Friday to get some gloves and look at the Shift 2. I looked at the Shift 2 and also at a Shift 3 at the suggestion of the sales person. The Shift 3 has a lot of extra features that make it worth the extra money in my opinion. If Trek has the 2015 Shift 3's available in Black and Titanium colors why is Trek still showing the 2014 Blue Shift 3 on their website? The local LBS knew about the new colors also.
Breakawaycycling.com has the 2015 models on their website with the new colors for $659.
