Thanks, all. Alex, I had the seatpost on my previous mountain bike, but kept it when I sold it. I also have one on my Bianchi. It's not really anymore setback than some straight posts that have setback, but the bend does give a little compliance over the rough stuff. However, I do currently have the saddle as far back as the marks allow. I probably need a longer stem. I haven't really investigated fit on this so far. It feels good, so I'm leaving it alone, mostly. On the Bianchi, I run the same seatpost, but a longer stem and the saddle isn't as far back (the frames measure very close to each other). Fore and aft of the saddle is important when riding clipless, so I'll take the time to look at it soon. As for now, it feels fine. Did a 25 mile ride the other day with no lingering knee issues.
