  • Stiff, smooth-riding frame and race-oriented geometry allow super-responsive handling
  • At under 1,100g, the CAAD12 aluminum frame barely tips the scale
  • SAVE micro-suspension technology in the frame, fork and seatpost adds flex in certain areas to absorb shock and vibration, improving rider comfort, handling and control
