Norco 2021 Sight A3 29

2021 Sight A3 29
Regular price $4,499.00

By re-imagining how we design bikes, our engineering department shattered the status quo with the Ride Aligned™ design system, addressing how a rider’s centre of gravity impacts the bike’s performance and then built the Sight A3’s All-Mountain design and aluminum frame around that. 

The Sight A3 offers 150mm of RockShox Deluxe Select R travel in both 29 and 27.5-inch wheel options to suit every rider’s preference and is equipped with a 160mm RockShox Yari RC fork. The Shimano Deore drivetrain and 4-piston brakes keep things flowing and slowing, while the TranzX dropper post offers size-specific drop.
