◂ Rims ▸
The PRD28 series (28 mm external width) rims are constructed using premium Toray T700 and T800 carbon fiber, combined with a stable resin system to form a strong and lightweight foundation. The lay-up structure is further optimized by minimizing excess material wherever possible, while reinforcing high-stress areas such as the spoke holes. This approach achieves an effective balance between weight reduction and structural integrity. As a result, these rims deliver a lightweight build without sacrificing stiffness or strength.
The PRD28 series features a 28 mm external width (21 mm internal width) and are compatible with 700×28C-45C tires. Multiple depths are optional: 33 / 38 / 44 / 50 / 55 mm. Whether you prefer a shallow profile for climbing or a deeper rim for speed on flat terrain, the range offers a suitable option for different riding styles.
