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 takes the tried & tested clutch style internals, & addresses all of the problems that those hubs had infamously been plagued with in the past. It also features 3-point internals, an allen key inner axle for easy maintenance, adjustable slack & come equipped with Eclat's Viper nylon-fibreglass hub guards. section Product Specs HUB TYPE: Freecoaster AXLE: 14mm Male DRIVER: 9t DRIVE SIDE: Right Side Drive SPOKE HOLES: 36h WEIGHT: 671g (1.48lbs)
