I'm currently riding a Forte split rail saddle - came with my bike. It's "okay." But I am still finding that I get pretty numb after 25 min. Bugs me the rest of the ride. I've tries other saddles, like the Selle San Marcos and the gap is good but the rigidity tore me up in the gooch. I've been looking at the Adamo, but just on the shelf. It's a pretty price tag for something that might be a bust. I see them on a lot of TT bikes, so they must popular. For those who ride them, are they as helpful as they appear to be for "blood flow?" Are they comfortable (enough) when you're tucked and on the end of the seat?
