Eclat have oversized their popular Cortex hub. throwing in larger bearings usually found in their rear hubs to give the hub a smoother ride with less resistance.

Using the same design as it's predecessor the Cortex OS is built for riders who want unrivalled durability and performance. The larger bearings are designed to keep on rolling smooth even after years of heavy abuse. capable of taking much harder impacts too they're built to go hard.

The Cortex OS features a longer 35mm bolt to accomodate plastic pegs and to give a stronger female bolt setup.
