Norco Sight A3 150 MX – All-Mountain Full Suspension Mountain Bike

Norco Sight A3 150 MX – Built to Go Big, Pedal Efficiently

Whether you're carving down steep loam lines, dropping into an enduro stage, or embarking on an all-day alpine epic, the all-new Sight A3 150 MX is ready to perform. This mixed-wheel enduro machine features 160mm front and 150mm rear travel, built around a high-pivot VPSHP Horst Link suspension platform with an idler pulley for incredible rearward axle path and stability on demanding descents—all while maintaining climbing efficiency.

Inspired by Norco’s long-travel Range platform but tightened into a lighter, more agile, and pedal-friendly package, the Sight A3 is your go-anywhere, do-anything trail weapon.

And now, every Sight model includes a OneUp EDC Lite multi-tool integrated into the steerer tube—so you're always prepared when the ride gets real.

Key Highlights:

• High Pivot Horst Link suspension with VPSHP design for control and traction

• Mixed-wheel setup (29” front / 27.5” rear) for maneuverability and rollover performance

• 160mm RockShox Lyrik Base fork paired with 150mm rear travel

• Shimano Deore 12-speed drivetrain for smooth, wide-range shifting

• 4-piston Shimano MT520 brakes with oversized rotors for confident stopping

• Tubeless-ready wheels with Maxxis EXO+ tires for grip and durability

• Size-specific dropper post travel for optimized fit

• OneUp EDC Lite tool included in steerer
