In fact, my previous Chorus set was purchased from Texascyclesport. Forget if they charge for shipping. I don't mind purchasing Record but it seems paying more for less durability and quicker wear of the cassette.
One of the reasons I ended up searching European sites is that I am also trying to purchase a few Conti GP4000 tires. For some reason, the price of these tires in the U.S. is just not competitive, upper $50's as compared to mid $30's in Europe.
