Shimano Dura Ace 7600 Series Large Flange Track Hub - Rear From  £111.99

Addition to the product, wanted to share my shopping experience with Total Cycling, which was good.
Received order confirmation (i think auto/machine) and shipped within day or 2, package was delivered to NYC within a week. All worked as expected.
Combined their competitive price, my experience was great, particularly i am a foreign customer.
