Recently I began having problems with my saddle, or more precisely, my behind. It starts to hurt where my sit bones are after 45-60 minutes. It feels sore at first, but eventually it gets really painful. I've ridden this bike (Trek Madone 5.0) thousands of miles over the past 10 years, but the pain only showed up in the past two or three months. I had a complete professional fitting when I bought this bike. I've changed nothing, and until now it's been perfect. The saddle is the Bontrager Race saddle that came with the bike.
At first I thought it was my shorts. I had some high end shorts that I thought might have worn out, so I got some new shorts that seemed to help at first, but now it's back to the same pain in the same place.
Twenty years ago I was a 10,000 miles a year rider, splitting my time on road and mountain, and I never had this problem. Back then I would be on my saddle for seven hours, and I never had this problem. Today, I'm more like a 3,500 miles per year rider, but I can barely do one hour in my saddle without pain.
I don't have the same pain on my mountain bike, which has a Fizik saddle.
I was looking at new saddles, which might be a solution, but before I do that, I figured I'd seek some advice here. Maybe it's a fit issue? Something changed unknowingly? I know my way around bikes pretty well, but I don't know anything about body mechanics.
Okay, adding some responses to the comments:
The Fizik saddle (MTB) is almost 20 years old. That really surprises me, but it's a 2001 Santa Cruz Superlight, so it must be. That bike still feels new to me! That's not the problematic saddle, however. The Bontrager saddle on the Madone is.
I have lost 15-20 pounds in the last year or so. I thought that might have something to do with it. That I might have less "padding" on my rear, but would that last 2 months? I should have adjusted by now. I'm riding four to five days a week now.
I did a quick check of the saddle. There is nothing obvious that is cracked or broken. Bolts are tight. I twisted and pulled it, but I can't get it to move.
I think the solution is to get a new saddle.
