I was finding the saddle that came on my Trek was not only uncomfortable for my sit bones... but my tender bits were getting quite tender after an hour or so...
So I read some reviews online and purchased a replacement. The Sella Italia Diva Gel Flow is only slightly larger than my original saddle, but it has gel pads for the sit bones, and it is completely cut out in the middle... so there is no pressure on the tender bits.
I've been out on a few long rides with the new saddle and can highly recommend it.
I changed to a Sella Italia Pro Gel and it's fantastic. They make great bike seats!
Mine was about $250 at a LBS but I bought it for $98 including delivery from Wiggle,
