The BSD Swerve Hub boasts an ultra fast engagement that's made possible by its 150 tooth ratchet ring plus individually toothed pawls. Built for strength and durability from 6061-T6 alloy that's paired with a female 14mm 4140 heat-treated chromoly axle, the pedal gap on this hub is almost non-existent and the noise it creates is a loud buzz. The Swerve hub is perfect for tech moves where a small pedal gap really helps. The Swerve hub uses many of the same parts as the Back Street Pro hub, such as bombproof 14mm female bolts, chromoly cones, a massive female axle and super tought 6903 bearings. Hubguards are available separately for both non-drive and drive side. ###section### Product Specs HUB TYPE: Cassette AXLE: Female Bolts DRIVER: 9t DRIVE SIDE: Right Side Drive SPOKE HOLES: 36h WEIGHT: 464g (1.02lbs) Colour: Polished, Black; Size: RHD
