Review on Axle Action 10Sp Rear Retainers by Kyle Omaha

They are hardened and tempered but only mild carbon steel (no chrome molybdenum alloy steel). Also, the threads are 3/8'-26 (not the slightly larger diameter 10Mx1). So if you ride aggressively (hitting obstacles hard and/or taking big falls) you can flex this axle. From above there are many parts including: (1) axle, 175mm long (2) bearing cones (2) dust caps (preinstalled on cones) (1) spacer, 14mm long (2) hex lock nuts (2) hex flange nuts
