Rear High Flange Track Hub Fixed-Freewheel 120 mm Spacing Bolt-On (Classic Model)
Our Classic track hubs are available in two versions: high flange or low flange. They are available in 20, 24, 28, 32 and 36 spoke hole configurations (other spoke hole count options are available upon request). We also offer our track hubs with 2 bearing options: Classic Phil spec bearings which have full contact seals and have a 100% fill with our Phil Waterproof grease. Carbonyte Phil spec bearings are our low drag bearing option which have partial contact seals and have a 30% fill with our full synthetic Phil Carbonyte grease. Our Classic fixed-freewheel track hub has a weight of about 388 grams.
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 lock ring 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 any other manufacturers lock ring on our track hubs. The additional thickness can result in stripping of the lock ring and/or hub threads because there is not enough thread engagement. Please call us if you have additional questions.
