Thanks all - good info. I've been fitted three times on my tri bike. After the initial fit, I went to a LBS fitter recommended by my coach. At that point, I was having not so much saddle pain but more neck pain. I don't have all the technical details as to measurements available to me here, but to give an idea the fitter put a longer stem on my bike and basically raised me up to a less-aero position.

That worked for another year and then I started to have increased saddle issues. The second fitting was with another tri coach and we decided to put me back down into a more aero position, shorter stem and slight saddle to aerobar drop. I figured I was just going to have issues either way so might as well go with the more aero position and experiment with saddles. Which brings me to my current situation.

I also think my GI tract just doesn't enjoy being in aero position either. Half-iron races I am on the bike for about 2:45 and start having a lot of gas build-up, to put it bluntly and experience a lot of upper abdominal discomfort on the run and IM distance I start sitting up and changing position to help alleviate this (and the saddle discomfort), so am losing the aero benefits anyway.

So I guess I will just start trying road bikes - maybe get some measurement info and share it here - sounds like some good technical knowledge out there.

now I wish I could find a gynecologist who is into cycling. My gyn sees my issues and just says "you should consider biking less; take some time off". Really helpful.
