Follow your own route, wherever it may lead. With stable flat bar positioning and disc brakes, Roam Disc handles all types of terrain and unlimited adventures.

Key Performance Factors

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 EasyRide Tubeless 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.

  • 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.
