It's just because 16092 is new; when 13060 debuted this summer, it was also 47.99. It just dropped to 42.96 a week or two ago. 16092 came out a month or so ago, so it's still under "new" pricing.
Oh, interesting. I guess that's what happens when I come in "late" in the game. Thanks for all the help...now on to convince the wife that i need more cycling gear...
