Great thread. Thanks for starting it.
The Specialized Butt-o-meter told me what I already knew. 143mm wide saddles are perfect for me. I need something that has a flat profile side to side and a very flat profile nose to tail. Anything else and really bad things happen to me.
Fortunately there area TON of saddles that fit that description nicely.
Road bike: Specialized Toupe 143 saddles adorn 4 or 5 bikes. They made a version with a little more gel padding in the nose that I liked on rides where I was playing with the wind and in the drops most of the day. Fizik Antares seems to be my favorite, though. I’ve done dozens of 10+ hour days in the saddle on it and I’ve never had a single problem.
Cross/Gravel Grinder bike: Toupe 143 is really good here too, but I just tried the Adamo Breakaway. I’m training for Dirty Kanza 200, where I’m going to be not only on the bike for 15+ hours, but also using aero bars on a rough surface. Some of the roads have fist-sized rocks for the surface. The Adamo design is both comfy for my sits bones and also is kind to my gentleman vegetables even when I’m in the drops or aero bars on rough roads. I spent a little time getting the saddle position perfect the day I got it, then went on a 125 mile gravel grinder the next day. It was flawless. It felt weird at first, but I’m happy with how it works. I’m a little sad because these saddles are insanely expensive and more than twice the weight of my favorite Fizik.
Mountain bike: Everything about the Specialized Toupe 143 would be perfect for the mountain bike except that it is very sharp at the front. When the terrain gets REALLY nasty, I don’t want something sharp and pointy anywhere on the bike if I can avoid it. Specialized Phenom 143 is quite similar to the Toupe, but with a hair more padding and no sharp plastic nose. I’ve got a few of those. Specialized made one for a while with the Tri-tip (extra padding for time trial and triathlon bikes) that I LOVED. I’m bummed that they discontinued it. That is the saddle that I use for the really long mountain bike rides. It has good padding at the front, but the shell of the saddle has enough flex to be comfortable all day. The 143mm Specialized Avatar is a great fit, but lacks the flex and support of the Phenom or Toupe. It is more like sitting on a brick, even though it has more padding.
Sorry to go on. There’s a lot of science behind saddles and it is easy for me to geek out.
Do your homework. Get fit for a saddle. It will give you a good starting point.
Rock and roll.
