I currently have a Selle An-Atomica on my Surly LHT but am about ready to try something else...I have been playing around with the tilt etc. but just have not been able to get entirely comfortable with that cutout. Sit-bone wise it is great, but the shape of the cutout causes some soft tissue discomfort after a while and got particularly bad on my 40-mile ride this past Saturday (me being kind of wiped out by the end of that ride didn't help, I'm sure). I also have had a couple of rides where the edges of the saddle flared out and caused some discomfort, but that seemed to go away after backing the tension bolt out a little. I seem to remember someone on here recommending Rivet saddles but am not sure if their cutout would be any better or if I might be better off trying a saddle without any cutout (but it seems like things would get squished if you KWIM). Anyone who has tried both care to chime in?
