Norco Optic A1
Details
With 140mm/125mm of travel, the Optic condenses years of technology from long travel bikes into a lightweight package that’s as comfortable tearing 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.
GEOMETRY
Coming in five frame sizes (1,2,3,4,5) to support rider heights up to 6’5" (196cm), allows you to choose the frame size that best fits your body and riding preferences. Rear centres and seat tube angles are varied by frame size to ensure consistent rider weight distribution, and short seat tubes with long dropper posts keep the saddle out of the way on technical descents.
WHEELS:
Available with a 27.5" rear wheel, 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.
