Diamondback’s Interval provides a swift, efficient and aerodynamic ride, making it the perfect choice for the exciting world of triathlon. Its lightweight and stiff Diamondback 7005-aluminum frame delivers all your pedal power to the road and the aero wheels get up to speed fast and cheat the wind to keep you there. Meanwhile, you hide from the wind on the aero bars and fly down the road with the precision-shifting 20-speed FSA/Shimano drivetrain for the road's ups and downs. You'll also appreciate the quality Diamondback components including the supportive seat and lightweight bar, stem and post.
