Eclat Cortex Freecoaster Hub

The Eclat Cortex Freecoaster takes the tried and tested clutch style internals, and addresses all of the problems that those hubs had infamously been plagued with in the past.

The first issue was the internal friction mechanism. A typical Clutch system hub uses x2 small balls on springs to apply friction to the inside of the hub shell, allowing the hub to engage. These small balls often wear out, causing damage to the hub and eventually end up in the hub slipping and cease working. Eclat took this system and modified it to use x3 points of friction which is not only incredibly durable but also more stable than other clutch style freecoasters.

The biggest issue with clutch style freecoasters was always that they generated “play” over time. When the clutch threads into the driver, it acts like a vice and clamps the large drive side hub bearing, and ultimately will cause large loads on that bearing causing it to weaken and become loose. Eclat solved this issue by using a special “c-clip” which sits freely behind the non-drive side bearing, preventing the force of the clutch from damaging the bearings and destroying them.

The Eclat team asked for a hub with a large slack setting, so the Cortex comes out of the box with just under 1/4 crank of slack, however, this is fully adjustable and can be made much smaller by adding small spacers behind the clutch, which are included with the hub.
