Overview

The Aurum Killer B Carbon was designed in conjunction with Norco's World Cup DH teams past and present and proven on the World Cup stage. This 650B-wheeled race bike represents the cutting edge of Norco's engineering and design capability and brings together all of our most advanced carbon, aluminum and mountain technologies. The Aurum - Latin for "gold" - earned its name by turning the most challenging terrain features into advantages over other riders.

Seconds at the start gate feel like an eternity. Mind and body are pulsing — in perfect sync. Your line gives you the edge you need; your bike will help you stick it.

Advanced Ride Technology

Advanced Ride Technology, or A.R.T., is the direct link between engineering and experience. More than a single suspension platform, A.R.T. is a system that w...

Norco’s engineering team strategically manipulates pivot locations to precision-tune suspension kinematics, ensuring that every full suspension bike will excel in the environment it was designed for. For downhill applications, we increase rearward axle path for a more controlled ride over gnarly, unpredictable terrain. For cross-country we increase pedaling efficiency and small bump compliance for a faster, smoother ride.

A simple solution to a complex problem, Gravity Tune fixes the front-centre/rear-centre ratio across all frame sizes, effectively optimizing geometry for eve... [read more]ry bike in the line. As a result, weight is always optimally distributed – regardless of rider height. Available only on Norco Bikes, Gravity Tune means equal ride characteristics and unrivalled control for all.

This ensures that a heavier rider on an extra large frame will experience the same ride characteristics as a lighter rider on a small frame. Though the process is labour-intensive, the result is worth the effort: optimal ride characteristics, performance and comfort for riders of all sizes.
