F9R WITH FFWD HUBS
The ultimate Time Trial and Triathlon carbon wheel set with the aerodynamic DARCâ„¢ technology. The 90mm deep carbon rims are the best choice for triathlon and time trials where maintaining speed is key.
DARCâ„¢ stands for â€˜Double Arcâ€™ which is the profile of the rim. It compresses air on the rim to create a faster airflow which reduces the drag behind the wheel.
The best hubs based on price and quality. High-end hubs with the least rolling resistance keep on going when you give them a spin.
