Features
Disc brakes
Reliable stopping power in all conditions, including wet and muddy.
Control Freak Cable Management
Control Freak is the lightest, quietest, most versatile cable management system. It allows any combination of shift and brake housing to be routed through the frame for clean aesthetics and an easily customisable set-up.
IsoSpeed fork
It's a one-two punch: generous ride-tuned sweep and shape increases compliance for a smoother ride, and unique dropout placement optimises the wheelbase.
300 Series Alpha Aluminium
Trek’s premium-grade aluminium is hydroformed into size-specific tubes that provide the perfect balance of stiffness and weight.
