Yes, and I even sent photos, but he didn't seem to see the issue in the photos. Since I keep the tension very tight, that seems to help a bit, but like Andrea, I am running out of room on the screw. Tom did say that was a warrantee issue, and I may send it back when I get to the end of the screw.
Since I have been off the bike for the last few weeks I haven't pursued it. I did do 20 miles on Sunday (ankle is finally more or less back to normal - yay) and after that ride I had a similar sensation of pressure at the very back of the saddle, but it wasn't as bad as before, but it was a short ride, too. I may have confused the issue with him by describing the pain as being my tail bone, but closer inspection shows that it can't actually be my tail bone. it';s a little hard to figure out how to describe it, but I'll pay more attention and try to be more precise when I email back. He was certainly very prompt with his response.
I have noticed that in the photos on the website, the saddles do not seem to have a obvious a bump as mine does, so I'm going to try and take a better photo and email it again to Tom. Except for the back of the saddle pressure, the saddle is perfectly wonderful.
(I am even toying with the idea of getting a red saddle, since I think the color will match my dark red bar tape!)
Keep calm and carry on...
