Evidently, if it's Dura Ace, there's a bit of titanium. And that, apparently, is why they cost $100 more than Ultegra.
I just ordered a set of Kysrium Elites and the LBS talked me into the Ultegra cassette - because they're $100 cheaper and not that much more heavier than the Dura Ace.

Should I get on the phone and change my mind back to Dura Ace?

yes, it is a little bit lighter as i think the 23/21/19 are ti, but wears faster, or so I heard. There is no way it costs 100 dollars more, however. You'd pay somewhere between 40 and 60 for Ultegra vs. Durace that is closer to ~90 bucks in LBS. Of course, you could go to and find a Durace cassette for 54 bucks, likely less than what LBS would charge you for an ultegra one.

Cassettes are not a permanent component on your bike. They wear relatively fast if you put in the miles, so why get durace? you end up paying 1 buck a gram for something in the middle of your wheel and not out on its circumference where it'd matter.

I just put a Dura-Ace cassette on my wife's bike last night and was amazed at how light it is compared to our Ultegra cassettes. Between the two of us we have 4 Ultegras. I bought the D-A from Performance for $70 + shipping. Think I'll buy another. The trick is to find a lightweight 16t to put in the middle.
