Am 300lbs, 6'3, and am having no luck in the saddle department. I can't find anything I can tolerate for more than 6 miles or so, it's the only thing holding me back from really increasing my range.
So far, tried most of the Selle gel saddles, the RX, the ones with the cut out's, etc. Tried a Serfas. Even tried a few women's seats thinking maybe a bit wider would help. That was not correct. :)
The local shop has the B-17 saddle, but looking at it, it's rock hard and has rivets all around, it looks like a torture device :) I would imagine it has to break in, but good lord what painful miles those must be.
