Selle San Marco Azoto MTN Gel. This is the steel railed version. It is a bit shorter, with all of the advantages of the Ti version. Due to the slightly shorter length, this saddle is actually lighter than the Ti version. I bought the saddle hoping that more gel would be better, but for me that is not true. None the less, this is an extremely popular saddle. I have ridden it ~3 times for less than 100 miles total, still have original box. I can send pictures if interested, just email me privately at gonzo@triathlete.com. $65 with shipping.
