Recently bought the evolution off Craigslist. My previous saddles were a Selle Italia Titanium Flite with gel insert, and the classic Selle Italia Flite. I really like the evolution. I don't get the twin knives or sitting on rails sensation that others have reported. It seems to fit me just fine. I've yet to do a ride on it over 40 miles but I should be doing that soon. I'm interested to see how if feels after a longer ride.
