When the Eclat team asked for a simple & durable freecoaster hub with a larger slack setting than most, they got to work on developing something totally new. The Eclat Cortex Freecoaster Hub takes the tried & tested clutch style internals, & addresses all of the problems that those hubs had infamously been plagued with in the past. Built with a 6061-T6 alloy hub shell that's paired with a hollow bore, hardened & heat-treated chromoly male axle ensuring those parts are incredibly strong & durable. It also features 2 high-quality bearings & bushing driver, high-performance durable bearings in hub shell making sure everything rolls real smooth, updated 3 point internals allow for much smoother crankflips & comes with Eclat's Viper & Gong nylon/fibreglass hubguards. section Product Specs HUB TYPE: Freecoaster AXLE: 14mm Male DRIVER: 9t DRIVE SIDE: Left Side Drive SPOKE HOLES: 36h WEIGHT: 671g (1.48lbs)
