Revolutionizing Cycling Efficiency: Introducing the Ovalsized™ Jockey Wheels from Ratio Technology

Here at Ratio, we prioritize efficiency in every product we create. And our latest creation, the Ovalsized™ Jockey Wheels, is no exception. Using the latest biomimicry techniques, we’ve taken inspiration from dinosaur eggs to optimize the local curvature at a continuum of points around the circumference of each jockey wheel. This results in maximum efficiency being achieved twice in each jockey’s rotation cycle, when the reduced articulation angle of each engaged chain link decreases fatigue and induces psych by up to 37%.

Each 20 tooth jockey wheel is designed specifically for use with a 40 tooth chainring; not only does peak efficiency occur four times per cycle – helping you over top dead centre – but the variable chain take-up preloads the derailleur’s cage spring, increasing chain tension to propel you forwards. However, it is important to note that as the Ovalsized™ jockeys induce cyclic variations in B gap, we recommend only shifting when the upper jockey wheel is at 67 degrees rotation relative to datum for peak shift performance. It may be a bit of a learning curve at first, but trust us – you’ll get used to it soon enough.

The Ratio Ovalsized™ Jockey Wheel system is now available at ratiotechnology.com for £1,234/€3,421/$3,142. And keep an eye out for our upcoming Ceramic Ovalsized™ Jockey Wheels – choose from porcelain, terracotta and bone china. Just remember that we cannot warranty terracotta and do not recommend dropping any of them!
