Maybe that guy in front of you every week is running  Z1s....

          That's right...our HextremeZ1 racing hubs have been high quality affordable flip flop hubs for almost 10 years. They are perfectly matched for our AC888 freewheels  They were developed to be strong enough for the big boys but light enough for the younger class racers.  Precision CNC machined from 6061 T6 forged aluminum, they are even stronger than those 'billet' hubs you hear about. They are available in  hollow CrMo axles as well as lighter aluminum axles. High or low flange...28 or 36 hole...we have the answer to your need for speed...our HextremeZ1 racing hub!
