Press Release:
At Ratio, we pride ourselves on creating products that are efficient, reliable and easy to use. Our latest product, the Ovalsized™ Jockey Wheels, is no exception. Using cutting-edge 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. 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 specifically designed for use with a 40 tooth chainring. Not only does peak efficiency occur four times per cycle – helping you over top dead center – but the variable chain take-up preloads the derailleur’s cage spring, increasing chain tension to propel you forward. Please 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 take some time getting used to it at first but trust us, you’ll get there!
The Ratio Ovalsized™ Jockey Wheel system is available now at ratiotechnology.com for £1,234/€3,421/$3,142. Coming soon: Ceramic Ovalsized™ Jockey Wheels in porcelain, terracotta and bone china options. Note that we cannot warranty terracotta and do not recommend dropping any of them!
