General Information
These are custom made hubs by one of the great bike builders in North America during the days of the six day races.. Doc Mortem had raced at the Pan-Am Games near the early turn of the century and then went to work for CCM building bikes for Willie Spenser and other performance riders of the 20's. He started making his own hubs as well. He went on to build track bikes for many Canadian, American and European riders  in the six day circuit in the North East races. These hubs are milled from solid blocks of billet aluminum, 40 front and 36 rear. Typically for track they have no seals and ran with oil instead of grease. The inch pitch cog is Constrictor.

Morten was a fixture in the arenas during the sixes not only as mechanic but also as race doctor, patching up the sleep deprived wounded when accidents occured.
