Press Release
Here at Ratio, we prioritize three aspects in every product: efficiency, efficiency, and efficiency. Would it have been more efficient to say that once? Not when it comes to our latest product, the Ovalsized™ Jockey Wheels.
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 of our Ovalsized™ jockeys. Maximum efficiency is 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.
Please note: 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’ll be a total arse at first but don’t worry – you’ll get used to it.
The Ratio Ovalsized™ Jockey Wheel system is ovalailable (see what we did there?) now at ratiotechnology.com for £1,234/€3,421/$3,142.
Coming soon: Ceramic Ovalsized™ Jockey Wheels. Choose from porcelain, terracotta and bone china. Note that we are unable to warranty terracotta, and do not recommend dropping any of them.
