A tri-spoke rear wheel for the maximum aero advantage in time trials and triathlons. 1030g
The Black Inc THREE is as close to a front disc while still being able to turn. The reduction in rotating spokes directly reduces the large surface area of the tri-spoke wheel, creating the sail effect and decreasing drag.
In fact, it can even add lift in some cases during real-world racing when the airflow deviates from the normal direction. This outcome is most likely to be seen during higher yaw airflows and gust conditions found during the many real world races such as Kona. In these conditions, where a standard spoke wheels begin to stall, the Black Inc THREE continues to thrive, giving you the maximum performance across a broad range of wind conditions and gusts.
