Through systematic innovation in structure, materials, technology, and equipment, SPEDAO has developed a fully proprietary integrated cassette and multi-material composite chainring. In the coming year, we will launch the high-performance "SPEDAO" gearbox. Our produced cassettes and chainring products are characterized by "six highs and one light": high strength, high toughness, high wear resistance, high transmission performance, high aesthetic appeal, high cost-effectiveness, and lightweight. At the China International Bicycle Exhibition, our cassette won the "Innovation Gold Award" at the 28th China Cycle in 2018, and our chainring won the "Innovation Gold Award" at the 29th China Cycle in 2019.

SPEDAO has established a rigorous quality assurance system. In February 2024, the company passed the ISO9001:2015 Quality Management System certification. Our integrated cassette is certified by the U.S. GCC and the EU GPSD.
