ERO Sports is an industry leader in Bike Fit and Aerodynamic Testing
This ain't no bike shop bike fit! Ero (pronouced "aero") Sports is one of the top bike fit studios in the world. Cyclists and Triathletes come to us to find their optimal position, not some generic position a bike shop will place you in.

Ero is also an industry leader in aerodynamic testing influencing product design, positioning, and equipment choice for the very best in the world. Utilzing both wind tunnel and Alphamantis technologies, there's simply no one in North America with more experience testing athletes and equipment.

Lastly, Ero fits more women than anyone in the world. In fact, over half our clients are women. We understand the unique issues women face. It's not supposed to hurt!

Brandon McNulty - World Time Trial Champion

"I just got done at the wind tunnel with my team and they said my position was spot on and I have some of the lowest drag numbers they've seen so I just wanted to thank you for being awesome at what you do and getting me set up so well!"

Rafael Galvan

"Can't say enough good things about Jim Manton. Prior to seeing Jim I couldn't stand being in aero on my TT bike for more than 30 min, first long ride after my fit with Jim and I comfortably pulled a 4hr ride. I was able to carry a higher power average by about 20 watts!"

Danielle Lyons Turrentine

"Jim Manton is not only an amazing bike fitter, but an amazing human as well. I can honestly say I felt like I was in company of a life long friend during my entire session. I just did 25 miles today after my fit and it felt like I was in a different body on a completely different bike. I can't give enough accolades to Jim!!!!"
