Details
The Helix' lightweight and strong aluminum frame is designed for women just getting into mountain biking. Its low top tube makes it easy to put a foot down and features a 100mm travel suspension fork to increase control on bumpy trails. A wide-range 24-speed drivetrain ensures you always have the right gear when climbing steep hills or cruising along flat paths, and powerful mechanical disc brakes provide excellent speed control, even in wet weather. Brake levers and shifters are easy to reach thanks to the taller front end and riser handlebar, putting you in the perfect position to steer the 27.5 x 2.25 CST Patrol tires toward your destination.
