I've had an R3 for a few months now and have about 3500 miles on it. It is a lot of fun. That pretty much sums it up. Quick, aggressive and very light. Not as smooth riding as my Moots SL but again, this bike is a lot of fun to ride.
Specs - DA10 with the following exceptions: FSA carbon compact crank, Zero Gravity Ti brakes. Deda newton bar and stem, Selle Italia Carbonio seat, Zipp 303 Wheels. Came with Ouzo pro fork and FSA carbon seatpost,
