Enve took a unique approach in their development of the System 6.7 wheelset, collaborating with aerodynamicist Simon Smart to design a wheelset using front- and rear-specific rim shapes to optimize the interaction between wheels and frame. Enve’s development was guided by the concept that a fast wheel isn’t the result of a single element, but a combination of factors and they believe they’ve created the fastest, most stable wheelset available.

The 6.7 wheel system uses a 60mm tall, 26mm wide front rim and a 70mm tall, 24mm wide rear rim. The goal was to create an integrated system, taking into account the fact that front and rear wheels are not affected by wind in the same manner.

Enve and Simon Smart focused on stability in the development of the System 6.7 wheels, but Enve isn’t just copying existing technology. Smart’s claim to stability fame stems from his intimate knowledge and extensive time in the Mercedes GP wind tunnel. He used the knowledge of transient (unsteady) aerodynamics gained in his years as a Formula 1 engineer and applied the concepts to race wheels. Smart designed a way to measure steering torque in response to changing crosswinds, and used this data to design a rim shape that reacts most favorably to quickly changing wind angles.

Smart and Enve delved into the interaction between wheel and frame. The 6.7’s were tested with multiple frames, enough that ENVE is confident that their wheels are the quickest on the most popular frames available.
