It was the one that came stock on my Allez, whatever that is. I got the fly last fall, and it feels nicer on my sit bones, but hasn't helped with the numbness. My shorts are pearl izumi, I'm not sure what model. Probably the cheapest ones. I just ordered the performance century shorts, as I've heard good things about them, but I'm not optimistic. Mind you, I'm a college student, so assos is not an option.
