PHi: The Golden Ratio of Performance,Engineered for Performance Balance
Top-Tier Quality, Affordable Pricing, Localized Service & Paintless Eco Carbon Tech
PHi (Φ) is not a symbol we borrowed — it is a principle we engineer by. In high-performance cycling, every gain comes with a cost:
lighter means weaker, stiffer means harsher, faster often means heavier. PHi was created to solve this contradiction.
PHi hail from the same Xiamen manufacturing facility as the world’s leading European and American carbon wheel brands. Built with identical production lines, premium raw materials and stringent QC standards, we deliver authentic top-tier quality straight from the source. What’s more, we bring this elite-grade craftsmanship to every rider with accessible, affordable pricing and professional localized service – the perfect blend of global premium quality and tailored local support.
We believe everyone should experience the thrill of ultimate performance. Our mission is simple: to make high-end carbon fiber products, once reserved for elite athletes, available to all passionate cyclists. “Explore the Limits of Carbon” is not just our tagline; it’s our commitment to relentless innovation.
1. Reduce 120-180g CO₂ emissions per pair of wheels, eliminate painting pollution, zero VOCs released, embrace green cycling
2. Save 40-60g weight per pair, lighter weight directly boosts acceleration and climbing efficiency for a smoother ride
3.Retain original carbon fiber weave texture, no coating peeling risk, 30% improved durabilityPrecision-molded one-piece forming, ready-to-use right out of the mold, no redundant processes, back to the authentic carbon fiber texture
