Interval Carbon

Riding on the weekends and maybe to work on occasion is a great way to gain some fitness, but that heavy old bike you’ve got in the garage just isn’t that much fun. The Interval Carbon is here to lighten your load and help you tap out a faster rhythm when you’re pushing on the pedals. The feather weight carbon monocoque frame delivers a fun, nimble ride and the Performance Hybrid Geometry puts you in an upright position and makes sure you stay comfortable whether you’re cranking crosstown or just jetting down to the store. The Performance Carbon fork quiets the chatter of choppy roads and always delivers smooth, confident handling. Factor in the smooth shifting Shimano 10-speed Tiagra drivetrain, powerful Tektro disc brakes and improved traction from the Schwalbe Spicer tires, and you’ll discover a whole new way to get around.


  • Hand built Interval carbon monocoque frame with Performance Hybrid Geometry delivers lightweight, responsive ride
  • Performance Carbon fork for smooth and precise handling
  • Shimano Tiagra 10-speed Rapid Fire shifters and rear derailleur for smooth, reliable shifting
  • Disc brakes and wider tires for improved safety on city streets
  • 700c Disc Wheels
