The Norco Sight A3 is an aluminium frame mountain bike that is built to be versatile and aggressive. The Norco Aluminum frame is designed with all-mountain geometry that is longer, lower and slacker for fast, aggressive riding. The Gravity Tune design fixes the front-centre/rear-centre ratio across all frame sizes, effectively optimising geometry and rider weight distribution for every bike in the line.

Suspension is king for the Sight A3, designed using the A.R.T. suspension system which delivers high-end suspension performance for superior climbing and descending capability. The system is optimised specifically for all-mountain riding. The updated Rockshox Yari Boost Fork w/Motion Control - (150mm travel for 29”) and trunnion mounted Rockshox Deluxe RT Debonair rear shock will give you excellent control and help you navigate all the bumps on the wildest trails. Also new in 2019, the 11-speed SRAM drivetrain and Maxxis High Roller II tyres will help you climb and descend with smooth efficiency. When you’re pushing the limits on the trails you need to be able stop in any conditions, and the Shimano hydraulic disc brakes with 180mm rotors will give you unrivalled stopping power rain, hail or shine.

The Norco Sight A3 is an all-mountain bike for the keen rider that wants to push themselves uphill, downhill and everywhere in between. This bike is an exciting and fun ride, made possible by the intelligent design and range of quality features. SRAM components are lightweight and flawless, while the Rockshox suspension combines with the norco’s A.R.T suspension design to provide an excellent mountain biking experience. The Norco Sight A3 is a great choice for someone after a versatile all-mountain bike that ticks all the boxes.
