  • Specialized Captain Sport tires lend a perfect knob pattern for diverse conditions
  • Light and durable double-walled alloy rims are tough enough to handle the rough stuff

  • Shimano Alivio 9-speed rear derailleur and Rapidfire trigger shifters for reliable, high-end performance
  • Shimano crankset with forged alloy arms and Octalink-splined BB interface means greater durability and better shifting performance
