About Us
Precision-engineered in Ellington, Connecticut. Built for riders who demand more.
Rotation Engineering didn’t start in a bike shop. It started in a race shop.
Long before our name was etched on a bottom bracket, we were building championship-grade components for motorsports. Founder Seth Carlson spent over two decades crafting precision parts for the most demanding race teams in the world—Formula 1, IndyCar, NASCAR, and Rally. In those environments, there’s no margin for error. Everything must be perfect. And durable. And fast.
But even with that pedigree, Seth saw something missing in the cycling world. As a rider himself, he experienced what many serious cyclists do: component failure under load, loose tolerances, short lifespans. The parts available just didn’t meet the standard he knew was possible. They were made for recreational use—not racing, not real stress, not real riders.
So in 2021, he set up shop in Ellington, Connecticut, and brought his motorsports mindset to cycling. Rotation Engineering was born with a single goal: to apply motorsports precision to the parts that make or break a bike’s performance—bottom brackets, hubs, headsets, and bearing assemblies. If it spins, we engineer it better.
From the Track to the Trail
Our roots run deep in motorsports. With over two decades of experience building parts for NASCAR and IndyCar, we’ve seen what true performance demands. We apply that same race-proven mindset to cycling—because serious riders deserve components engineered for the toughest conditions, not just casual weekend spins.
Tested by Us. Trusted by You.
We ride. We race. And we test every product the hard way—under real conditions, far beyond the limits of ordinary cycling gear. From dry desert trails to mud-caked mountain climbs, if it survives our abuse, it’ll thrive on your ride.
Performance You Can Feel
Rotation Engineering components are built to motorsports-grade tolerances—down to ±0.0001″. We test our materials against stress loads ten times the industry standard and use sealing systems inspired by 200mph racing environments. That’s why our parts don’t just work—they last.
Why We Build in the USA
We believe in supporting the community that supports us. Every part is built under our roof in Ellington, CT. No outsourcing. No compromises. Just elite-level craftsmanship from a team that cares about every detail.
