Get your daily dose of singletrack. With a lightweight frame, 130mm suspension fork and 27.5 wheels with high-volume tires, this hardtail offers loads of traction, speed and fun on the trail.

Key Performance Factors

Integrated aerodynamics

AeroSystem Shaping, a result of extensive CFD analysis and dynamic wind-tunnel testing, creates the best aerodynamic performance at every yaw angle. A truncated-ellipse airfoil shape delivers the best overall aero performance.

TOTAL CONTROL

Integrated rim-brake technology delivers outstanding braking power in most conditions. The integrated Giant WheelSystem further improves control with a 65mm deep rear rim and a shallower 42mm front rim for added control in crosswinds.

UNRIVALLED EFFICIENCY

The frameset, including the integrated stem and handlebar, features best-in-class weight and stiffness. Increased frame stiffness allows the rider to reach and maintain higher speeds with less effort.

Weight
The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.

Every effort has been made to ensure accuracy throughout this website. However, Giant reserves the right to change bike specifications, features, prices and colours without prior notice.
