Kuvaus: Specialized OSBB BB30 x42 bottom bracket . It changes BB30 to "shimano" standard 24mm axle . Brand new,in original package, never installed. Taken from new Specialized frame box ( legally ) comes from Crux cyclocross frame, so have better sealed industrial bearings . I switched for Rotor crank & bb.
