The Shell is machined from 6061 aluminium and features a hollow 14mm Crmo Axle. The driver is also supported from the outside by a huge bearing making this hub ultra reliable and maintenance free ###section### Product Specs HUB TYPE: Cassette / Coaster Switchable AXLE: 14mm Male DRIVER: 9t SPOKE HOLES: 36h WEIGHT: 583g / 20.55oz
