Key Performance Factors

Agility and control

Smooth-riding comfort

The D-Fuse seatpost and suspension fork absorb road shocks and vibrations.

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.
