I purchased the whole 6800 Ultegra bike. It will be completely torn down and built up with some parts being changed. Obviously will try to get it as light as I can while keeping things durable and dependable for racing. Will probably upgrade things as budget allows. Will ride Ultegra for now as its been a long time since I had a Shimano group. May switch over to Sram Force/Red at some point. The new Ultegra does look and feel nice. Look forward to putting some miles on it. Onto some photos and weights:

As of now the wheel choice will probably consist of the new Ksyrium Pro Exalith SL and November Rail 52. I also have a set of hand built H+S wheels that I can use for poor weather/gravel.
More to come...
