2018 Norco Threshold A Tiagra

Developed amid the rugged landscape and abundant precipitation of Canada’s Pacific Coast, the new Threshold Aluminum is perfect for any rider looking to get down and dirty at their first cross race. Featuring the same race-proven geometry and ARC technology of the Threshold Carbon, the Threshold Aluminum delivers race-ready performance along with all the versatility you expect from a ’cross machine.

 A premium double-butted aluminum frame shares the same raceproven geometry and compliance technology as the Threshold Carbon, but adds additional rack and fender mounts for increased versatility. You'll love the trust Tiagra drivetrain and the sure-stopping Tektro Spyre brakes, and the supportive Norco XC Race saddle is well-suited to a blistering 'cross competition or a blazing-fast commute. Fast, fun and ready for muddy mayhem.
