Hello all, this is my first post so just bare with me here. I just measured my sit bones using my highly scientific method of getting a piece of cardboard and sitting on it while puting my feet up on a chair so I could get them to stick out some. When I got off the cardboard there were dents in the cardboard but they were both like the size of a pepsi can. So I measured from the center of both and came up with 5.5 inches which converts to 140mm sit bones. My new bike that I just bought a Cannondale Cyclocross 5 came with a Selle San Marco Ponza Power which is straight up torture on my booty. So finally my question is, #1 is my highly scientific method of sit bone measuring pretty reliable and if so what saddle might be good for a 30 yrs old, 5'7, 185lbs gal, with 140mm sit bones? I'm pretty much a newbie to cycling, so I understand I'm going to have some discomfort until my booty is broke in. I'm really kinda leaning towards the Brooks B17 standard or the Brooks Flyer. Also, can I use the flyer for road biking!! I'm not super aggressive in my postion, but my bike does have drop bars? My booty will thank you for any ideas!!!
