I really want to buy one of these in a few months. I'd either try and get a 2015 model on sale or the 2016. Im asking for some help regarding the changes:
The 2016 Grade Carbon Ultegra is mostly the same while the 2016 Grade Carbon 105 changed from R685 to R785 brakes.
Also, the 2016 Grade Carbon 105 changed from R685 brake levers to RS505 brake levers.
Are these 2 changes downgrades, upgrades, or sidegrades? Or really not much difference at all in real world application?
