The Shadow Conspiracy BTR (Bolt Type Raptor) Cassette Hub is made of 6061 hardened aluminum with 2 oversized bearings for added strenght and a longer lasting rolling life. It includes a 1pc, 9t chromoly driver with polymer bushings and is available with 36 holes in left or right hand drive. The hub holds a 17mm nickel-chromoly axle that accepts 14mm bolts that are readily replaceable. The BTR non-drive side hub guard is designed specifically for the BTR Cassette hub. The guard replaces the steel cone, maintaining the 110mm hub spacing so there is no need to stretch your frame.
