Developed for a purpose
We innovate to improve user benefits. All Scope products are developed for a specific purpose and to improve your riding experience.
Aerodynamic Drag
Drag is the aerodynamic force in the opposite of the riding direction that is slowing you down. It is generated by every component of the wheel including the rim, spokes and hub.
You can think of drag as the aerodynamic resistance, this resistance originates from two components, pressure drag and skin friction drag. They are induced by the shape of the wheel and friction between the molecules of the air and the wheel.
As from 15 km/h onward, drag is the greatest resistance you must overcome, where the front wheel has a drag contribution of ± 10% of the total system drag.
By minimizing drag, you can achieve higher speeds with the same amount of effort or maintain a given speed with less effort. As speed increases, the importance of overcoming drag becomes more significant and so the importance of the aerodynamics of your wheel.
Side-wind stability
Side wind stability can be explained as the sensitivity of the steering moment with respect to the side wind. In other words, the force or effort that you need to apply to your handlebar to keep your bike straight in case of a cross winds. The larger the angle of the airflow (yaw angle) and the stronger the wind force, the more you must constantly adapt to ride straight in the desired direction.
The optimization of the side wind stability consists of two components. First, a low steering moment is essential to decrease the influence of side wind. Next, it is required that the steering is predictable, this is achieved by creating a linear relation between steering moment and yaw angle. Both of these criteria ensure a predictable and so controllable handling of your bike, resulting in longer periods in the aerodynamically optimal position and higher speeds.
Lightweight
The importance of lightweight wheels can’t be underestimated, it effects your riding experience in many ways.
Lower weight contributes to a better climbing performance. Climbing requires the cyclist to overcome the force of gravity, and a lighter wheelset makes it easier to ascend hills and mountains with less effort.
Lighter wheels result in quicker acceleration, which is beneficial in scenarios such as sprinting or responding to changes in pace during a race. Cyclists can accelerate more rapidly, making it easier to stay with a fast-moving group or respond to attacks.
Lighter wheels contribute to more responsive and agile handling. The reduced mass means that the bike responds more quickly to steering input, making it easier for cyclists to navigate corners and changes in direction.
Rolling resistance
Rolling resistance on a bike refers to the force that opposes the forward motion of the bike as it rolls along the ground. It’s the resistance that the tires encounter as they deform and recover with each revolution. Rolling resistance is a significant factor in determining the overall efficiency and speed of your bike, mainly influenced by tire choice, pressure, and size. Reducing rolling resistance is important as it directly affects the effort required to maintain speed and the overall efficiency of your bike.
The design, construction, and materials of the tire affect how much it deforms when in contact with the ground. Softer and more flexible tires generally have lower rolling resistance. In comparison to a tubular or clincher tire, tubeless tires don’t have an inner tube which cause friction between the tire and tube. Furthermore, the flexible casing construction of a tubeless tire allows the tire to conform better to road surfaces. Flexibility contributes to lower rolling resistance, especially on rough or uneven terrain.
Wider tires
Tubeless tires can be run at lower tire pressure compared to clinchers without risking a pinch flat, particularly when using wider tires. Lower tire pressure allows for increased grip and comfort and a larger contact patch with the road, reducing rolling resistance. The larger contact area can distribute the load more evenly, reducing deformation.
Lateral Stiffness
Lateral stiffness directly influences your bike’s handling, responsiveness, and overall efficiency. The lateral stiffness of your wheels is influenced by the flange distance, number of spokes, the later flex of the spokes, spokes tension and the height of the rim.
A lateral stifff wheel is essential for efficient power transfer from your pedal stroke via the drive train into the wheel resulting in forward motion.
Climbing and sprinting often involves standing high-power effort on the pedals and applying significant force. A laterally stiff wheel ensures that the power generated is efficiently transferred into forward motion, allowing you to climb and sprint more efficiency.
Lateral stiffness ensures that the bike responds accurately to the rider’s input, especially during cornering, descending and quick changes in direction. A lateral stiff wheel helps maintain precise handling and allows the rider to control the bike with confidence.
Durability
Durability is crucial for carbon wheels as it directly affects the performance, safety, and overall riding experience. Our wheels are developed to be durable, reliable, build to last and withstand stresses at extreme circumstances providing you with a confidence riding experience.
To realize a durable and lateral stiff hub set, the optimum size for our specific application and exact position of the bearings have been defined at an early stage of the development process.
To reach the perfect balance between high durability and low rolling resistance together with our development partner SKF we customized the type and amount of grease used in our bearings.
The optimized design of our ratchet system provides a reduction of stresses on the ratchets. Combined with our Diamond carbon Like Coating, this allowed us to utilize the more lightweight titanium material alongside steel to produce our ratchet system, resulting in further weight reduction.
Our 2:1 spoke pattern ensures equal spoke tension in our wheels, preventing uneven distribution of forces, causing the wheel to deform under load and negatively impacting the overall performance and stability of the wheel.
