Giant Roam Disc 4
Details
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.
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 tires 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.
TECHS AND FEATURES:
- ALUXX ALUMINUM TECHNOLOGY
This Performance level frame material features 6061 alloy with single-butted tubes to produce strong, lightweight framesets for a variety of different bikes and riding styles.
- D-FUSE SEATPOST
The proprietary “D” shaped composite seatpost damps vibration, resulting in a smooth, compliant ride.
