Follow your own route, wherever it may lead. Roam is built for all types of terrain, so your choices are unlimited. Smooth roads, rough roads, dirt paths or trails, now you can ride it all with comfort and style.

With its confident, flat handlebar positioning and lightweight ALUXX aluminium frame, Roam Disc gives you all the best qualities of a mountain bike and a road bike. Its front suspension and new D-Fuse seatpost absorb road shocks and vibrations, adding comfort and control. It has powerful disc brakes and durable components, so it can take some bumps on rough city roads. And the fast rolling 700c wheels with Giant’s tyres can handle smooth roads or dirt, making it a great choice for town-to-trail adventures.

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.
