Giant roam 3 disc.


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 EasyRide Tubeless tyres can handle smooth roads or dirt with less risk of a flat tyre, making it a great choice for town-to-trail adventures.


Agility and control
Updated flat-bar frame geometry puts the rider in a position that balances efficiency with stability, and disc brakes give you added control on rugged roads or dirt.

Smooth-riding comfort
D-Fuse seatpost and suspension fork absorb road shocks and vibrations, for a smoother ride quality across a range of surfaces.

Integrated rack mounts
Compatible with rear racks, allowing easy cargo capacity for daily trips or longer treks.
