I get a sore tailbone whenever I ride on the stock Bontrager saddle that came on my Treks (road, mtn). I changed out my bikes to Terry's (Liberator Y, I think and a Butterfly--I don't remember which one is on which bike, but the wider one is on the road bilke.). It wasn't too bad (the pain) in the first year I had the mtb, probably because I just didn't know any better, but it was still there.

What's relevant about that is the other day my road bike was in the shop, and my mtb had a flat. So I hopped on my son's Trek mtb with the stock Bontrager saddle, because I had limited time to ride anyway.

It quickly became apparent that a narrow saddle is the WORST for me. I might be feeling my sit bones on the saddle, but it is clear that the saddle is impacting my tail bone. It took a few days to not feel that achy pain in my bottom even just from sitting down in a kitchen chair, and I only rode that bike for 6 miles!!

His saddle is narrower than the WSD ones that came on my Treks. I suppose the contrast of the much narrower saddle made it so obvious. You probably have too narrow a saddle. I'd get a wider one.
