Product Details

2017 Norco Aurum A7.2

Poise and grace aren't typically used to describe a blazing DH run, but one ride aboard Norco's Aurum might have you whistling about the refined composure of this speed fiend's character. 27.5-inch wheels provide a quick and stable foundation, while the aluminum frame is lightweight and tough enough to take a beating. Norco chose to design the Aurum around the real-world benefits of a 7-speed cassette, using 142mm rear axle spacing to optimize the chainline and increase heel clearance, while keeping tighter gear ratios for race-winning runs. For the Aurum A7.2, you get the solid-performing SRAM GX drivetrain with an 11-25T 7-speed cassette, SRAM Guide R brakes with 200mm rotors, and a Race Face Chester crankset. Schwalbe Magic Mary Bike Park tires chew through chunder, while the WTB STP I29 rims laced to Novatec sealed bearing hubs let you rail without worry. Trail grading duty is assigned to the RockShox Domain Dual Crown fork, and the RockShox Kage RC coil rear shock returns controlled landings and big-hit compliance season after season.
