Ochain's Active Spider Eliminates Pedal Kickback - REVIEW

Want the super-smooth feel of riding chainless while still being able to pedal? This clever device offers a unique solution.

Rating: Vital Review

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. 

On many bikes, chainstay growth during suspension compression causes the crankset to rotate counter-clockwise. This is also known as pedal kickback. By allowing some spring-loaded rotational movement within a reimagined chainring spider, the Ochain device is claimed to automatically isolate your transmission from your suspension while descending. We're joined by Vital tester, MTB Savant, in the video above for an in-depth review and his ride impressions.

What's The Bottom Line?

Our tests confirmed the claims. With an Ochain device installed there is a general feeling of isolation from your feet, and it noticeably takes the edge off sharp hits – especially on low-speed, technical descents. The device made a marked improvement in small-bump sensitivity, compliance, and the back end felt like it wasn't getting caught up as much. Added cost, weight, complexity, and dead space while pedaling are the major drawbacks. The ideal customer is someone riding a bike with lots of chain growth who is focused on descending capabilities.
