2025 Norco Optic A2 29er Dual Suspension Mountain Bike

Whether you’re ripping fast, flowy singletrack, powering up punchy climbs, or railing corners, the all-new Optic A2 elevates short-travel trail riding to the next level. Its high-pivot design, increased rearward axle path, and idler-driven VPSHP suspension layout provide remarkable confidence and capability—both uphill and down.

Plus, every Optic now includes a OneUp EDC Lite tool conveniently stashed in the steerer tube, so you’ll never be caught off-guard on the trail.
