The Cab v2 Freecoaster Hub features a 6061 aluminum shell with offset flange heights and new and improved axle and nylon clutch retention system. By replacing the traditional spring/ball system, the new hub requires less maintenance and is easier to disassemble for adjustment and maintenance. The nylon retention system also reduces internal drag and has less rolling resistance than traditional designs. Includes replaceable Cab v2 drive and non-drive side nylon guards.
