OXO HB-675 Hub

Hub OXO HB-675 Flip-Flop is designed for fixed-gear and single-speed bicycles, offering smooth rotation and minimal maintenance thanks to its sealed bearing system. The hub body is made of anodized aluminum alloy, providing a light weight along with corrosion resistance.

Featuring a flip-flop hub design, one side can be used for fixed gear (cog + lockring) and the other side for a freewheel, providing flexibility to suit your riding style. The steel bolt-on axle ensures secure and stable installation on the frame.

The product includes a 17T steel cog and lockring, ready for use in a fixie configuration.

Calculating Spoke Length

For a 50 mm rim profile, use the Strummer Spoke Calculator. Rim profile height alone is not sufficient; the rim ERD, hub dimensions, number of holes, and lacing pattern are required. Any unavailable data must be measured together with a mechanic.

7-Speed Freewheel Compatibility

The OXO HB-675 rear hub uses a Fix-Free threaded configuration: one side is for fixed gear and the other side is for a freewheel. Supports 7-speed freewheels.
