On May 5, 2025, at the 33rd China International Bicycle Exhibition held at the Shanghai New International Expo Center, Hunan Suoao Technology Co., Ltd.'s "Super Eco-friendly Crank," developed and designed by the company, stood out from nearly 1,600 exhibiting companies worldwide and won the "2025 CHINA CYCLE Innovation Award Gold Medal" for its groundbreaking environmental concept and innovative technology.。
Professional competition-grade road bike crankset, 170mm in length, with a rated torque of 210 N·m. It utilizes high-strength, high-toughness aluminum alloy (strength > 800 MPa, yield strength > 750 MPa) developed in-house by Suo Technology for sports equipment. The total weight of a pair of cranks is only 265g ± 2g. Compared to top-tier carbon fiber products of the same type in the world today, it achieves a weight reduction of 5-10% while maintaining the same strength and stiffness. Compared to world-class aluminum alloy products, it achieves a weight reduction of 40-50%. Product features: Through extensive use of triangular structures and optimal material distribution, supported by finite element analysis and calculations, it perfectly achieves equal-strength design and effective stiffness enhancement. Combined with the self-developed ultra-high-strength aluminum alloy for sports equipment, it achieves a perfect combination of super lightweight design and environmental friendliness (recyclable materials) without using carbon fiber. It is particularly suitable for professional training and competition, ultimately realizing Suo Technology's dream of "allowing ordinary cyclists to enjoy the performance of professional competition-grade products at an exceptional price-performance ratio."
Technological breakthroughs are leading the industry's green transformation. This crankset utilizes lightweight composite materials independently developed by Suoao Technology, combined with low-carbon manufacturing processes, achieving a material recyclability rate of over 85%. Through structural optimization and material innovation, the crankset's weight is reduced by 30% compared to traditional metal components while maintaining equivalent strength. Its core technologies include: Recyclable material system: Utilizing 50% recycled engineering plastics and carbon fiber composite technology, the production process reduces energy consumption by 40% compared to traditional processes; Modular design: The crankset components can be quickly disassembled and recycled, extending the product's lifespan and reducing resource waste; Lubrication-free technology: Self-lubrication is achieved through surface treatment processes, avoiding the oil contamination problems of traditional cranksets.
This authoritative recognition highlights its leading position in the industry. This year's exhibition, themed "Empowering the Future with New Technologies," attracted international brands such as Shimano and Decathlon. The innovation award selection focused on three dimensions: "low carbon and energy saving," "technological content," and "market potential." Speedio Technology's super eco-friendly crankset stood out from 70 shortlisted products, becoming the only domestically produced crankset to win the gold award.
During the exhibition, the crankset was prominently displayed in the innovation achievements exhibition hall. Its environmental performance and technical specifications have been certified by TÜV Germany, and its carbon footprint is 58% lower than similar products.
Company Strategy and Industry Impact: Founded in 2022, Hunan Suoao Technology specializes in the research and development of lightweight sports equipment. Its patented technologies, including modular flywheels and multi-material chainrings, have already entered mass production. This award-winning product will drive the global promotion of the company's "SPEDAO" high-performance drivetrain components, with an expected production capacity of 500,000 sets by 2026.
Industry experts point out that the application of this crankset will accelerate the transformation of the bicycle industry chain towards a circular economy, providing low-carbon solutions for electric bicycles, shared bicycles, and other related fields. The Secretary-General of the China Bicycle Association stated: "Speedo Technology's innovative achievements mark a technological breakthrough for China in the field of core bicycle components, setting a new benchmark for the industry's green development."”
