These BMX hubs are 36-hole small flange, loose-ball bearing steel hubs. The rear hub will work with single speed thread-on freewheels that are 16t and larger that are threaded 1.37x24 (not included). The hubs have a steel shell and are black in color. The OLD is 100mm front and 110mm rear and the axles are 3/8".
These are very basic economy hubs, they are not high end by any stretch of the imagination.
