  • Flak Jacket protection and a grooved tread make the 28c Specialized Nimbus tires perfect for city or open road use
  • Strong and light Sirrus alloy, double-wall, disc-specific rims
  • Strong, reliable Tektro Draco hydraulic disc brakes for sure stopping and control in any weather with any load
  • FSA compact 9-speed crank with 50/34 configuration means ample gearing and crisp shifting
