A dedicated cyclocross race bike, the Norco Threshold shines in the wild and unforgiving environments that make CX races such a spectacle to behold. Much like the racers it was designed for, this bike lives to out-compete and thrives in harsh conditions. Pedal it, carry it, push it – whatever it takes to get over the finish line before everyone else. If you’ve got CX in your blood, the Threshold is your ticket to ride.

Norco 5 Point System
  1. Tapered head tube and full carbon fork: all work as a powerful system to maximize front-end stiffness, delivering a highly responsive ride experience.
  2. Internal cable routing: keeps cables tucked safely out of harm’s way, reducing wear and prolonging cable life while ensuring smooth shifting and predictable braking in any conditions.
  3. PressFit 30 BB: ultra-lightweight and easy to install, Pressfit 30 bottom brackets help to prolong bearing life and accommodate stiffer cranks for greater pedaling efficiency.
  4. Disc brakes: deliver unmatched modulation, improved clearance, confidence-boosting stopping power and maximum control through mud, sand, snow, grass and gravel.
