Phil Wood Phil Wood Low Flange track hub front
For optimal performance, we recommend using the Phil Wood track cog. They are offered in both 1/8″ and 3/32″. Our specification for the threading is 1.370 x 24 tpi, but Phil Wood hubs will accommodate most high quality cogs. If, during installation, the cog jams or binds, STOP. Forcing a cog onto the hub will result in irreparable damage to the threads. As with any cog installation, lubricate both the cog and lockring threads. Some cog manufacturers are making cogs that are not ideal for use with Phil Wood hubs due to their thickness (which is generally a result of plating). For this reason, we do not recommend using Surly or Euro-Asia cogs with our track hubs. The additional thickness can result in stripping of the lockring and/or hub threads because there is not enough thread engagement.
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.
