On the morning I visited Xiamen Honji Weiye Industrial Co., Ltd., also known as STREN, the sky was heavy with rain, and the humid air wrapped around me like a quiet welcome. Parked at the entrance, two Maybachs offered the first hint: this wasn’t just a factory—it was a flagship of ambition in the global cycling industry.
Inside, I quickly discovered that STREN is more than a manufacturer. It’s an innovation hub, a place where advanced carbon fiber technology, precision engineering, and future-ready production converge to shape the next generation of high-performance bicycle components.
An Office Designed for Momentum
Welcomed by Peter, a warm and insightful company representative, I was led to the meeting room on the third floor. The office space was vast, modern, and thoughtfully laid out. One striking feature? A dedicated gym for employees—a clear signal that STREN invests in the well-being and energy of its workforce, not just its machines.
It was easy to picture passionate engineers stepping off the treadmill and back into a brainstorming session on the next breakthrough in wheel design.
The Engineering Behind the Ride
Back on the ground floor, Peter introduced me to STREN’s core products in a sleek showroom just off the lobby. The company employs between 1,300 and 1,400 staff, with over 100 focused solely on R&D. Their specialty? Carbon fiber spokes and rims, built for high-performance cycling.
One of their latest spoke models weighs just 1.7 grams—yet withstands a tensile force over 4,000 N. That ultra-light yet ultra-strong combination delivers greater power transfer and acceleration, perfect for competitive riders seeking every possible performance gain.
As for the rims, STREN skips traditional decals and paints. Instead, logos and designs are molded directly into the carbon during production, eliminating excess weight while offering a sleek, minimalist aesthetic. Some rims even include raised detailing, seamlessly combining visual impact and technical efficiency.
Peter also highlighted their so-called “breathing wheels”—a poetic term for a highly practical innovation. These rims feature variable wall thicknesses: thinner areas for controlled flex, thicker zones near spoke nipples for reinforced strength. The result? A wheel that’s both responsive and incredibly durable.
Inside the Production Powerhouse
Photography was not permitted in most production areas, but the impression remains vivid. STREN’s facility is a highly synchronized operation, where humans and machines work in precision harmony.
6 production lines churn out roughly 4,300 rims per day. That’s over 1 million rims annually. They also produce over 1 million carbon spokes per month. What’s more, a new automated production line currently in testing is expected to quadruple output using only one-third of the labor. STREN is also expanding to a new facility five times larger than the current one, with plans to reach 5 million wheels per year.
Integration as a Competitive Edge
One key differentiator? STREN builds not only its products—but also the machines that produce them. This vertical integration gives them control from design to delivery, reducing lead times, increasing quality, and enabling them to scale innovations rapidly.
When a new rim or spoke design is finalized, the custom tooling and machinery are already in place—ready to roll, literally.
Testing, Down to the Micron
I was also shown a glimpse of STREN’s testing laboratory, which felt more like an engineering lab than part of a traditional factory. Here, products are subjected to:
. Impact tests (to simulate rough terrain)
. Balance tests (for smooth ride performance)
. Tensile and fatigue testing
And even CT scans, which detect micro-defects invisible to the eye
Not only are wheels tested, but entire frames and assemblies, ensuring that every component meets stringent performance and safety benchmarks.
Conclusion: The Future is Already Spinning
As I stepped back into the cooling rain, I left with a strong impression: this isn’t just a company. It’s an ecosystem of innovation, where thousands of lightweight carbon components come together with precision and vision.
Xiamen Honji Weiye (STREN) isn’t following trends—it’s creating them. With its blend of advanced engineering, vertical integration, and bold investment in scale and people, STREN is pedaling at full speed toward a future where performance, quality, and efficiency define the new standard in cycling manufacturing.
