About Ratio

Ratio Technology was founded in 2018 by Cambridge Engineers Tom Simpson and Felix Barker.

Our aim is to develop ground-breaking drivetrain products: We believe that bicycle drivetrains can be improved. Along the way we’ve set our minds to creating the parts we want to ride on our own bikes. We hope you enjoy them.

Felix is a former rider of the professional team, Cycling Team Friuli, where he also tested drivetrains for a well-known bicycle groupset manufacturer. He has been British University and Three-Up National Time Trial Champion.

Tom comes from a mountain biking background in the Lake District and builds Simpson custom steel frames. When he’s not cycling you’ll find him fell running, ski mountaineering or windsurfing.

Louis is Ratio’s inventory and shipping manager. Also based in the Lake District, Louis is a sailing instructor, windsurfer and mountain biker.

Will is a keen cyclocross and mountain bike racer. He’s also a Cambridge Engineer who has joined Ratio’s product development team.
