TAICHUNG CITY, Taiwan, Aug. 28, 2025 — J-Star Holding Co., Ltd. (referred to as “J-Star” or “the Company”), a prominent supplier of innovative carbon fiber and composite solutions used in various fields such as personal sports equipment, healthcare products, automotive components, resin systems, and R&D services, revealed today the introduction of QO Bikes. This new premium cycling components brand was established by its YMA subsidiary in collaboration with seasoned industry professionals Pablo Carrasco and Ignacio Estellés. Built on a foundation of innovation, QO is poised to set a new standard in high-performance cycling.

QO’s initial product offering includes three distinct sets of carbon fiber cranksets, meticulously engineered for road, gravel, and mountain biking. These cranksets, notable for their lightweight yet exceptional strength, underscore QO’s commitment to transforming cycling components through cutting-edge engineering. While the broader industry continued to develop aluminum products, Carrasco and Estellés were among the first to conceptualize and design carbon fiber cranksets, laying the groundwork for continuous innovation under the QO brand.

Having launched earlier this year, QO has already commenced shipping its products to various brands and retailers through its established distribution network across Europe, Asia, and Latin America. The company is now actively pursuing distribution channels within the U.S. market and intends to broaden its product portfolio with additional high-performance cycling components, integrating state-of-the-art materials, expert engineering, and designs centered on rider needs.

“QO embodies the inventive spirit and meticulous craftsmanship that propel advancements in cycling, and it forms a crucial part of our larger strategy to introduce our own innovative brands of sporting goods and other products to our valued customers,” commented Jonathan Chiang, Chairman & CEO of J-Star. He added, “We are honored to collaborate with Pablo and Ignacio—true visionaries in the cycling world—who have consistently pushed the boundaries of what is achievable in component engineering. Supported by YMA and J-Star’s extensive resources and global infrastructure, QO is strategically positioned for significant growth, continuous innovation, and to secure its place as an industry leader.”

Carrasco and Estellés are recognized industry pioneers, having previously unveiled revolutionary technologies such as oval chainrings and power meter cranks during earlier stages of their careers. Through QO, they unite decades of expertise with a novel perspective, striving to establish an unprecedented benchmark in cycling components.

Carrasco articulated, “Our objective with QO is straightforward: to develop cycling components that motivate and elevate the performance of both professional riders and dedicated enthusiasts.” Estellés further explained, “The name QO derives from the Latin phrase Quo Vadis—meaning ‘Where are you going?’—which encapsulates the very essence of cycling: its forward momentum, adventurous spirit, and boundless potential. With the backing of J-Star, we eagerly anticipate expanding, innovating, and sharing this journey with cyclists worldwide.”
