Mat Steinmetz is a highly regarded consultant and thought leader in the cycling and triathlon community, specializing in bike fitting, coaching, aerodynamics, and equipment optimization. He has worked with athletes at every level, from recreational cyclists and age-group triathletes to Tour de France winners and Ironman World Champions.

​

Steinmetz holds a Master’s degree in Exercise Physiology and Human Performance from Ball State University. After relocating to Boulder, Colorado—a hub for endurance sports—in 2007, he quickly gained recognition for his ability to leverage technology to make data-driven decisions that improve performance.

​

He joined Retul in 2009, a sports-tech startup, where he built strong consulting and coaching relationships with athletes that went on to win Tour de France stages and Ironman World Championships. In 2012, Steinmetz was named one of the top ten most influential people in triathlon, being dubbed the "speed technician."

​

In 2016, Steinmetz founded 51 SPEEDSHOP, a component business focused on optimizing the connection between bike and rider. While these products have been trusted by world-class athletes, including in the Tour de France, they are thoughtfully designed to serve riders at all levels—offering both performance and accessibility.

​

In 2018, after a successful career in endurance sports, Steinmetz pursued a new challenge by joining the world’s largest medical device company, working on product innovation in medical wearables and digital health technologies. This role broadened his perspective and sharpened his skills in product development, business strategy, and customer-centric innovation.

 

Now, after reflecting on his journey, Steinmetz is returning to his true passion: endurance sports. Armed with the insights and skills gained from his time in the medical device industry, he is bringing a fresh perspective back into the endurance world.

 

With expertise spanning bike fitting, coaching, and product development, Steinmetz has firmly established himself as a leading authority in endurance sports.
