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.
