S-All Carbon Ultra H2 D30-50 Disc Brake Carbon Spoke Wheelset
This is a new wheelset that Superteam just launched this year. It is equipped with shark fins and wave rims, 3.2mm ultra-lightweight carbon spokes, 54T ratchet hub, and ceramic bearings.
54T Ratchet Hubs
54T means the ratchet has a smaller engagement angle, which can transmit power faster than 36T or 24T ratchets. The smaller engagement angle (about 6.67°) reduces idling when climbing, sprinting, or accelerating, improving riding efficiency. For road bikes, triathlons, climbing, cross-country, and other scenarios, the 54T ratchet provides a more agile power response, giving riders an advantage in high-speed shifting or complex terrain. Compared to ratchets with higher teeth (such as 108T), the 54T maintains a faster response while also taking into account durability and ease of maintenance, and is less likely to cause excessive wear of the pawl.
CS11-3.2-SL Spokes
CS11-3.2-SL is a high-strength carbon fiber composite material with a width of 3.2 mm, a length of 255 mm, and a weight of 1.75 g (excluding nuts). It is currently the lightest carbon spoke in the world.
We conducted tensile tests, tensile damage tests, and lateral compression tests on this spoke. The results show that: the spokes are stable within the force range without sudden changes; the material strength and structural design are excellent and can withstand extremely high tension; the spokes can maintain a stable structure under high-speed cornering, lateral impact (such as wind resistance, bumps), etc.
Titanium Alloy Cap
The cap head and tooth cap are upgraded from stainless steel to titanium alloy.
Lightweight: The density of titanium alloy is about 4.5g/cm³, which is 58% of the density of steel, 7.8g/cm³, to reduce weight and improve pedaling response.
High tensile strength: suitable for high-tension wheels to ensure structural stability under high-speed riding or complex road conditions.
The wheelset weighs only 1290g
The weight of the carbon fiber wheel set of 1290g is already super lightweight, which is very competitive among the wheels of the same level, especially suitable for climbing and long-distance riding. The lightweight design also reduces the moment of inertia of the wheel set, making the acceleration response faster, and it is also suitable for aggressive riders.
Ceramic Bearings
The front wheel uses two ceramic bearings: ceramic bearings have low friction, smoother rotation, improved rolling efficiency, and reduced energy loss. Since the front wheel is subjected to less force, the use of ceramic bearings can maximize smoothness and increase cruising speed.
The rear wheel has three ceramic bearings and one steel bearing: this can ensure efficient transmission, reduce pedaling losses, and increase power output; steel bearings are more impact-resistant than ceramic bearings, suitable for high-torque transmission, and improve durability.
"Shark Fins" and Wave Rims
The bionic technology of the wave circle originally came from the nodule on the front edge of the humpback whale's pectoral fin. Experiments have proven that this bulge can bring better aerodynamic benefits. Rugged surfaces have better aerodynamic effects than smooth flat surfaces, reducing air resistance. SUPERTEAM has optimized the design of these dimples based on the characteristics of the aerodynamic wave circle and adopted a "shark fin"-shaped matrix arrangement to better integrate these dimples and the wheelset.
