Roam 4 Disc

With its flat handlebar, comfortable upright positioning and smooth, powerful disc brakes, Roam combines the best qualities of a road bike and a mountain bike. Now you can follow your own route wherever it goes.

The ALUXX aluminium frame is designed for rugged versatility and a controlled, comfortable ride. Its front suspension and DFuse seatpost absorb road shocks and vibrations. It has powerful disc brakes and durable components, so it can take some bumps on rough city roads. And the fast-rolling 700c wheels 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: The D-Fuse seatpost and suspension fork absorb road shocks and vibrations, and puncture-resistant tyres let you run lower pressure for a smoother ride quality and a reduced risk of flats.

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