The Sight Carbon is a versatile trail killer, featuring modern All-Mountain geometry and suspension kinematics for a fast, stable and playful ride on a wide range of terrain. Balanced climbing and descending capability combined with grin-inducing playfulness and nimble handling make the Sight the ideal accomplice for any aggressive All-Mountain rider.

More than a single suspension platform, A.R.T. (or Advanced Ride Technology ) 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.

Traditional frame designs disregard rear-center lengths when changing size, leading to sub-optimal riding positions for some riders. Gravity Tune fixes the front-centre/rear-centre ratio across all frame sizes, effectively optimizing geometry and rider weight distribution for every bike in the line.

By increasing tube profile dimensions in proportion with frame size, Norco engineers are able to calibrate frame stiffness to the weight of the prospective rider. This ensures that a heavier rider on an extra large frame will experience the same ride characteristics as a lighter rider on a small frame.

Norco's SmoothCore process enables us to maintain precision control over all of the inner surfaces of our carbon frames, which is particularly critical at complicated, high-stress areas like the head tube and bottom bracket junctions. At the heart of SmoothCore is our innovative mandrel system.

Norco's carbon frames are manufactured with only the highest quality materials, right down to the resin we use to hold everything together. Our superior quality ArmorLite resin produces an exceptionally strong bond that enhances frame strength and increases impact resistance.

Our GIZMO internal cable routing system keeps out water and debris, prevents any rattling, and allows for easy setup and maintenance.

Mountain bikes are designed specifically for off road riding, with strong frames and components, knobby tyres and a large range of gears. While performing best off-road, mountain bikes are extremely versatile, and suitable for a variety of recreational and commuter purposes. Entry-level mountain bikes are more suited to bike paths, parks, and light use on unsealed surfaces. Progressing through the range, mountain bikes become more suited to longer rides, and rougher terrain, with a focus on durability and performance. A cheap mountain bike makes also makes a great all round commuting option. Mountain bikes can be either hardtail (front suspension only), or dual suspension (suspension in front and rear). Carbon fibre frames achieve a huge advance in performance, as the material is extremely strong, light, and stiff, achieving maximum power transfer from rider to bike.

Mountain bikes can be used for many types of riding, from riding around town to endurance off-road racing. Mountain bikes now come in 3 wheel sizes: 26 inch; 27.5 (also called 650B); and 29 inch. Generally speaking, the smaller 26 inch wheel size offers a more responsive, agile ride. The larger 29 inch wheel size has the advantage of reduced rolling resistance over rough Australian terrain, which provides easier clearance of obstacles, and general comfort over the trail. The bigger wheels also offer more tread connected with the surface, helping to increase traction. 27.5 offers the ultimate versatility - the agility and handling of traditional 26 inch wheels, with the reduced rolling resistance and improved traction and stability of a 29er. 

Womens mountain bikes are designed specifically for female riders. Generally this involves a lower top tube and standover height, which makes it easier to dismount as well as plant your feet on the ground when extra balance is required. They also features womens specfiic saddles and braking and gear set ups more suited to smaller hands.
