Norco Optic A Frame Kit
Details
Whether you're ripping fast flowy singletrack, putting the power down on punchy climbs, or tearing the tires off in the corners, the Optic continues to push the boundaries of what's possible on a short travel trail bike.
The new Optic with 140mm/125mm of travel condenses years of technology from our long travel bikes into a lightweight package that's as ready to tear up climbs as it is tackling challenging descents. The VPSHP suspension layout provides increased rearward axle path and an idler to manage pedal feedback, keeping Optic's playful roots, while punching above its weight when the trails get rough.
Available with a 27.5" rear wheel (MX), as well as 29" in some markets. Swapping the linkarm and lower shock mount with the "Missing Link Kit" converts between 27.5" and 29" to let you pick the wheelsize that suits you best, while maintaining geometry and kinematics to ensure consistent fit and bike setup.
