Its a Fizik K:1 seat I got off ebay for 1/3rd of retail. Its not too bad, but it is quite firm with just a thin layer of gel padding. It all depends on what kind of seat your butt likes. After trying dozens of seats, Ive settled on the Arione series/shape. Combined with bib shorts/chamois it works just great. My one grip is that the rails are wrapped in a rough type of material that would scratch/wear a hole in clothing. I just ended up taping up the rubbing part of the rail with some black electrical tape.
