I have test rode an R3. 56CM, Ultegra 10 speed, and lower end wheels, 19Lbs. Stiff frame like a CAAD, and yet a soft ride like a carbon bike without the plastic noise/feel.
Frame and Alpha Q fork is about the same as a Specialized Tarmac, Super Six Himod, or Madone frame.
Trying to convince the CFO I really need one.
