Chainrings

If you've ever ridden a full-suspension bike without a chain, you likely noticed an improvement in its suspension performance. After watching some incredible chainless downhill runs on the UCI World Cup circuit, this Italian brand dreamt up a way to provide the benefits of riding without a chain, with a chain.

By allowing some spring-loaded rotational movement within a reimagined chainring spider, the Ochain device is claimed to automatically...
