The 700C Carbon Rear Disc Wheel for Triathlon & Time Trial – D29 is engineered for riders, bike brands, and performance-focused cycling projects seeking maximum aerodynamic efficiency, stable power transfer, and reliable race-day performance. Built with high-modulus Toray T800 carbon fiber and a paint-free UD carbon finish, this rear disc wheel is designed to reduce unnecessary coating weight while maintaining the stiffness and durability required for demanding triathlon and time trial applications.
With a tubeless-ready structure, 22.5mm internal width, and lightweight build options, the D29 offers an excellent balance of speed, control, and modern tire compatibility. It is well suited for triathlon bikes, TT bikes, and aero-focused road race setups.
We also support OEM and ODM customization for cycling brands, distributors, and wheel builders. Contact us for detailed specifications, sample options, and custom branding support.
