Cannondale's CAAD8 Tiagra 6 is the ride of choice, whether you're a seasoned roadie or heading out on your first group ride. Cannondale's mastery of aluminum frames is evident when you inspect the shaped, large-diameter tubes with super thin-wall profiles. This creates an optimum blend of low weight and stiffness for awesome efficiency and incredible road feel. The Cannondale Ultra carbon fork offers precision steering and mutes road vibrations for a super-smooth ride. The quick-rolling Maddux wheelset with fast and grippy Schwalbe tires make the miles fly by. And, Shimano's Tiagra drivetrain features light action, easy shifting, and twenty hill-topping gears that make any climb easy. Cannondale dual-pivot brakes provide sure-fire stopping power, and a stem, bar, seatpost and seat from Cannondale ensure that rider comfort and ergonomics stay high.
