Shimano Dura Ace 7600 Series Large Flange Track Hub - Front From  £117.99

I have new wheels built with Dura Ace 7600 track hub, tested 100km. It’s awesome! I was not sure whether i can feel difference between old hub, which 1/10 in terms of price. It’s night and day. The difference is far beyond expectation.
Feeling is old hub is rolling (nothing wrong) , 7600 feels sliding/surfing! I am not sure this is the case with all dura ace hubs, but if you ride fixed gear, worth to try/check. Drawback is price, if you are serious and ready to invest an instrument, may be worth, this hub should last life long with good maintenance. And as far as I checked the price Total Cycling offer was good (best for me)
