The BSD Swerve Cassette Hub has ultra fast engagement thanks to its 150 tooth ratchet ring and individually toothed pawls. Built from 6061-T6 alloy drilled for 36 spokes with a female 14mm 4140 heat-treated chromoly keeping the hub super strong and durable. The pedal gap on this hub is almost non-existent and the noise it creates is a real loud buzz. The Swerve Cassette Hub also comes equipped with bombproof 14mm female bolts, chromoly cones, a massive female axle and super tough 6903 bearings. ###section### Product Specs HUB TYPE: Cassette AXLE: Female Bolts DRIVER: 9t DRIVE SIDE: Left Side Drive SPOKE HOLES: 36h WEIGHT: 464g (1.02lbs) Colour: Polished, Black; Size: LHD
