I replaced the saddles on both bikes fairly quickly. It took me a few experiments to get it right but I found a saddle I really like (Fizik Arione) and now have it on both bikes.

BiK, funny you should mention the Specialized saddle as a source of particular agony. I don't know which model you tried -- but it seems to be such a popular saddle. However, my bf has a Specialized Alias right now, and neither of us are wild about it. I will say that it's light years better than my first experiment after discarding the Bontrager that came on my road bike though -- the Terry Damselfly. Not the right saddle for me at all!
