I got the saddle this afternoon and put it on the bike just in time for my group ride. I just got back from it, and the stats were 30 miles at a pace of about 17mph. Flats, hills, sprinting, and just lazy pedaling.
Comparing it to my recent B17, it initially felt "harder" on my sit bones. About halfway through though, I seemed to find the comfort spot and all was well. I did not shift around nearly as much as my other saddle (Velo crap) and I did not experience any discomfort! Truly amazing, and I am really looking forward to getting some more miles on it. I'm toying with the idea of loosening up the lacing just a smidge, but will leave it as is for now.
