The Optic Aluminum 9 is a fast-pedaling 29" trail bike that rides with just the right mix of cross country efficiency and all mountain playfulness. Progressive trail geometry has been carefully tuned across each frame size to give every rider the same optimal fit and ride quality, while A.R.T. suspension delivers both efficient climbing and lively, capable descending. Ride your trails, your way - and ways you never thought possible - faster, with more control, complete confidence and that feeling of becoming at one with the bike. Ride the Optic and see the trail differently.

Effective seat tube angle
With traditional frame designs, engineers adjust front-centre lengths for each frame size but use a single, fixed rear-centre length. This approach leaves riders of certain body types in a poor position when standing. Poor body position leads to uneven weight distribution and negatively affects traction, control and overall performance and ride characteristics.
A simple solution to a complex problem, Gravity Tune fixes the front-centre/rear-centre ratio across all frame sizes, effectively optimizing geometry for every bike in the line. As a result, weight is always optimally distributed – regardless of rider height. Available only on Norco Bikes, Gravity Tune means equal ride characteristics and unrivalled control for all.
Advanced Ride Technology, or A.R.T., is the direct link between engineering and experience. More than a single suspension platform, A.R.T. is a system that we optimize for each intended use. Norco’s engineering team strategically manipulates pivot locations to precision-tune suspension kinematics, ensuring that every full suspension bike will excel in the environment it was designed for. For downhill applications, we increase rearward axle path for a more controlled ride over gnarly, unpredictable terrain. For cross-country we increase pedaling efficiency and small bump compliance for a faster, smoother ride.
A.R.T. delivers four major benefits to riders: enhanced pedaling efficiency, increased square-edge bump compliance, improved braking performance and progressive suspension characteristics. These benefits are balanced in different proportions based on intended use, creating a ride experience unique to each model.Enhanced Pedaling Efficiency
A.R.T. is designed to effectively manage chain growth to create anti-squat forces that counteract the forces responsible for suspension bob. The result is an incredibly efficient pedaling platform, superior power transfer and unmatched climbing ability.Increased Square-Edge Bump Compliance
Rearward axle path describes the rear wheel’s trajectory as a bicycle moves through its travel. A.R.T. uses a pronounced rearward axle path that enables the wheel to travel both rearward and upward, up and out of the way of obstacles.Improved Braking Performance
A pronounced rearward axle path also allows a bike’s suspension to remain fully active when pressure is applied to the brakes. A.R.T. delivers powerful, predictable braking with fully active suspension and superior traction at all times.Progressive Suspension Characteristics
A.R.T. suspension uses a progressive leverage ratio curve, meaning that the forces required to engage the shock increase progressively as the shock moves through its travel. The first part of the stroke is very supple and effectively absorbs small to medium-sized impacts. Toward the end of the stroke, the shock becomes progressively stiffer, resulting in a ‘bottomless’ feel. To the rider, this progressive curve is experienced as consistent, predictable suspension at every point in the travel.
The fully proprietary GIZMO system features two-piece GIZMO plugs that create a tight seal, blocking water and debris from entering the frame. GIZMO plugs pinch and hold cables firmly in place, preventing any rattling at entry and exit points. They also enable the rider to pull cables taught so that they can be prevented from rattling around inside the frame.
