    The Optic C3 is a fast short-travel carbon fiber trail bike with the agility and confidence you need to look further up the trail.

    Using Norco's Ride Aligned™ design system to create its fit, geometry and suspension kinematics, the Optic C3’s playfully aggressive personality is complemented by 125mm of rear travel via a full-custom RockShox Super Deluxe Ultimate DH rear shock and a 140mm Pike Select RC fork.

    Adding to its high-speed trail performance, the Optic C3 features a Shimano XT/SLX 12-speed drivetrain with Shimano MT6100 cranks. Shimano MT420 4-piston 203/180mm brakes control the speed, and the light weight, robust wheels feature Stan’s Flow S1 rims on Shimano Center Lock Boost hubs.
