Our Story

Redshift Sports was founded in 2013 by a team of mechanical engineers who also happen to be avid cyclists. From the beginning, we've focused on taking a different approach to product development - drawing on our own experiences and needs to create components that make a meaningful difference to the riding experience. 

Prior to starting Redshift Sports, the founders worked in a wide range of industries, from designing medical devices and baby strollers, to large-scale landmine clearance equipment and military aircraft. We drew on this extensive design, prototyping and manufacturing experience to bring our current line of products to market. 

In June 2013, we launched the Switch Aero System on Kickstarter, a crowd-funding platform that lets independent backers jump-start small businesses and projects. The response was overwhelming - people loved the idea of maximizing the versatility of their existing road bikes, and Redshift was born. 

In the years since, we have been busy bringing new and innovative products to market, such as the ShockStop Suspension System with ShockStop Stem (2016) and ShockStop Seatpost (2019). All of our products are designed, tested, and hand-assembled in our Philadelphia warehouse, where we maintain an uncompromising dedication to quality and customer service. 

We will continue to produce new products to help provide comfort and speed to your ride to help you go further and faster. We look forward to seeing you on a ride, at an event or hearing from you on our social media channels. 

Stephen Ahnert
Stephen signed up for the 2009 Philadelphia Sprint Triathlon on a whim, and after successfully not drowning during the swim, he was hooked. As a mechanical engineer, he prefers to optimize his equipment rather than train harder. Stephen's background is in nuclear power and children's stroller design - he dreams of one day designing a nuclear-powered baby stroller.
Erik de Brun
A high-school swimmer and collegiate pole-vaulter, Erik took to triathlon like a flying fish. He's consistently one of the first competitors out of the water and prefers single-loop bike courses that are entirely downhill. Erik is a mechanical engineer who has worked on everything from V-22 helicopters to landmine clearance equipment.
Scott Poff
Scott swam breaststroke in high school, and can be found frog-kicking competitors all along the eastern seaboard. A strong cyclist, Scott is currently experimenting with training plans that integrate large quantities of Belgian beer. He is also a mechanical engineer (seeing a theme here?) with a background in nuclear power.
Diana Balderson
As an artist, Diana immediately connected with the creative minds at Redshift when she joined the team. Now, she is a Diana-of-all-trades in charge of sales, customer service, and assembling products crazy fast. She’s also training for her next big art triathlon, which consists of showing her artwork along the East Coast, drinking complimentary wine, and a lot of socializing.
