The rotating wheels and tires represent a unique challenge. The fully reversing flow comes off of the spinning tire and interferes with the frame and fork that are close to the affected area. This is exacerbated by the trend towards riding on wider tires, which shows no signs of slowing down.
With the HANZŌ we carefully moved the airfoil sections well clear of the rotating tire, preventing the interaction effect and allowing both sections to perform optimally. Additionally, this approach accommodates up to 28mm tires. This design takes advantage of the aero benefits that result from having greater clearance around the tires, essentially reducing the effect a tire’s shape has on the airflow through the fork and frame.
The one piece fork’s width not only works with the rotating front wheel to improve efficiency, but at the rear, the seat stays are as wide as UCI regulations allow in order to smooth the airflow between rear wheel and frame, as well as airflow off the rider’s calves.
