Track hubs are available in the classic high flange or traditional low flange in 28, 32, and 36 spoke hole configurations (other spoke hole count options are availabe upon inquiry). Traditional spacings of 120, 126, and 130mm are available. Keirin (110mm) spacing is also available and the axles are adapted to the narrower 8mm rear axle dropout. Endcaps and washers for the Keirin hubs are knurled.
Conversion from your original axle type to another will require different axle ends and may require a different axle core.
