I ve been riding for about 11 mos and I ve tried alot of seats on my bike, some are too wide some are like boards, and even the b17 pinched my glutes on long rides , at 240 pounds my CD ars have found love.
I seem to fit the Fizik Aerone Ti, like it was made for me. My legs go up and down without any restriction and the seat flexes alittle from side to side if you slide back like your supposed to.
It looks like a brick but on the bike it gives just a little enough so those tender parts don't feel the Pinch.
I ve also noticed it seems to not allow me to slide around as much.
I managed to level the seat and it stil feels good.
If your a big guy or Gal and you haven't found a seat that sems to fit and feel great.
See if you can borrow a seat from your LBS I hear that some LBS have a red seat Loaner program.
I ve found my Seat...
ps I found a steal on Ebay for a Shop seat that Looks new only a few clamp marks on the metal
