Eclat's latest hub is based on the popular Cortex Coaster Hub but this one takes on the Cassette style. It's built from a 6061-T6 alloy hub shell that's paired with a hardened 14mm chromoly male axle that features a hex key inner axle for strength, durability and easy maintenance. It also features two high quality hub bearings with three durable driver bearings to keep everything rolling smooth. The Eclat Cortex Cassette comes with nylon Viper and Gong drive and non-drive side guards. ###section### Product Specs HUB TYPE: Cassette AXLE: 14mm Male DRIVER: 9t DRIVE SIDE: Right Side Drive SPOKE HOLES: 36h WEIGHT: 608g (1.34lbs) Colour: Black; Size: RHD
