Ultra H2 Carbon Spokes White Paper

1. Overview

Ultra H2 is a high-performance carbon fiber wheelset that Superteam is about to release. One of its core components, the CS11-3.2-SL ultra-light carbon spoke, uses advanced carbon fiber composite materials to provide excellent strength, durability, and stability. We conducted rigorous tensile, tensile failure, and lateral compression tests on the CS11-3.2-SL to verify its performance.

 

2. Technical Specifications of CS11-3.2-SL Carbon Spokes

(1) Model: CS11-3.2-SL
(2) Size: Width 3.2 mm, Length 255 mm
(3) Weight: 1.75 g (without nut)
(4) Material: High-strength carbon fiber composite material

3. Test Methods and Results

3.1 Tensile Test

Test Method: A universal testing machine was used to apply tension to the CS11-3.2-SL.
Test results:
(1) Tensile test value: 282 kg
(2) No slippage of spoke metal connectors
(3) The total length of spokes remains unchanged
(4) The test curve is stable

Conclusion:
(1) Spokes are stable within the force range without sudden changes
(2) The elastic deformation of the material is reasonable without plastic deformation or elongation
(3) Excellent strength, stability and durability

3.2 Tensile failure test

Test method: Use a universal testing machine to apply the ultimate tensile force until failure.
Test results:
(1) Destruction test value ≥ 320 kg
(2) Final destruction value: 432 kg
(3) Destruction mode: body damage

Conclusion:
(1) Excellent material strength and structural design, able to withstand extremely high tension
(2) Sufficient safety margin to meet the needs of high-intensity riding
(3) Good matching of connection point strength to avoid failure of local weak points

3.3 Lateral compression test

Test method:
(1) Tighten the spokes horizontally and apply 120 kg tension
(2) Apply pressure gradually in the vertical direction until it is destroyed
Test results:
(3) Destruction pressure value: 132 kg

Conclusion:
(1) Spokes can maintain a stable structure in high-speed cornering, lateral impact (such as wind resistance, bumps), etc.
(2) The wheelset has higher reliability in high-intensity riding and competitive competition environments

4. Conclusion and Prospect

The CS11-3.2-SL The ultra-light carbon spokes have demonstrated excellent mechanical properties in tests such as tension, extreme tension, and lateral compression, ensuring their reliability and safety in high-intensity riding, competitive racing, and other scenarios. In the future, Superteam will continue to optimize materials and manufacturing processes to provide cycling enthusiasts with higher-performance wheel products.
