Professional assembly included with every order - Norco is pleased to announce that customers can now purchase bikes directly from Norco.com and have them shipped to the Authorized Norco Dealer of their choice for professional assembly and pick up. Here's how it works.
It shouldn’t come as a surprise that the rugged landscape and abundant precipitation of Canada’s Pacific Coast is the ultimate place to develop and perfect a carbon fibre cyclocross bike. It helped us engineer the Threshold C’s mid-modulus carbon frame & fork with ample mud clearance and shock dissipation with size-scaled tubing, ovalized seatstays and bent chainstays for maximum CX performance.
The Threshold A1 features a Shimano GRX wide-range 11-speed drivetrain and hydraulic disc brakes with internally routed cables, so they won’t get clogged with mud after a lap in the sticky mud and snow. Shimano thru axle hubs are laced to WTB KOM Light i21 TCS Tubeless Ready rims, which support fast, sturdy Schwalbe X-One 33mm knobbies.
