Welcome to the first of a four-part blog and podcast series examining each of the four barriers to speed combated by Zipp's Total System Efficiency (TSE) wheel design: Wind Resistance, Rolling Resistance, Gravity (weight), and Vibration Loss.

Each episode features a different Zipp engineer discussing one of these barriers to speed. First, Zipp Senior Design Engineer John Leachman discusses the importance of wind resistance. John oversees Zipp's wind-tunnel research and is an avid triathlete and runner.
