AURUM A1

The Aurum Aluminum offers a DH-proven design in a premium aluminum frame, and is built to be the ultimate DH park rig, happily churning out lap after lap at your favourite gravity-fueled destination throughout the season.

Developed in collaboration with Norco Factory Racing, the Aurum A1’s World-Cup racing heritage will put any gravity junkie or passionate DH racer in the hot seat – at races and with your buddies during a day at the park.

The Aurum A1 features Gravity Tune, with rear-centre lengths that increase proportionately to the front center length for each frame size, achieving optimal body position and weight distribution for superior handling and control. The 6060-T6 frame includes strategic frame armour and integrated fork bump stops, with fender and shuttle guards for protection from day to day high speed riding and surprise get-offs.

Designed around 27.5” wheels for strength and stiffness, the Aurum A1 provides 200mm of supple travel with its Fox Performance Vanilla LSC rear shock and RockShox Boxxer Select fork. With a tough, reliable Shimano Zee 10-speed DH drivetrain and 200mm SRAM Code R brakes, you’ll have all the performance and reliability you need for a day at the park.

BIKE SIZING CHARTS

We design bikes that fit people; achieving a fit that makes you feel at one with your bike is our primary goal. To ensure the most comfortable fit for every body, we take proportions into account with our recommendations.

The size charts below provide recommended frame size based on the rider’s height. Where there is overlap, we include suggested sizing based on the rider’s proportions, as varying limb lengths can require different frame sizes for optimal fit.

The below size charts are for reference only.
