This is not going to be the typical "which saddle should I get" thread. Promise.

About me: 242lbs, 6'1", 110mm sit bone width (center to center), currently riding Selle Italia Flite Gel Flow Max saddle (150mm wide)

The Story
I rode 32 miles yesterday. My longest distance to date. Saddle felt great (normal sit-bone uncomfortableness) until the last two miles or so. It got really uncomfortable then. My previous "long" rides were 16-18 miles with no problems. This morning I barely got through 8 miles and had to get off the bike from sit-bone pain. None (or barely any) of the discomfort is genital numbness. It's all in the sit-bones.

I also have numbing on my left side, from sit-bone partially down my hamstring.

Could it be that I just need more saddle time for the pain to go away? Is it possible that the hamstring numbness is from a too-wide saddle pinching off the blood flow to the back of the leg?

I am thinking of going to a slightly narrower saddle (143mm), specifically the Romin Evo Expert. My hopes are that this narrower saddle will relieve the hamstring numbing, and still give good sit-bone support. According to the Specialized charts, this is the width I should be on anyway.

Is narrower the way to go? Is my head thinking about this correctly, or am I all whacked?

Thanks for any advice you all can offer to this newb.

If you go with the Romin Evo then I would not get the 143. Get the 155 as it's a rounded saddle and measured differently. If the Romin Evo doesn't work out for you them try the Chicane. A common cause of numb legs is having the saddle too high.

Are you sure your problem is the saddle, I have to agree with NWS Alpine...how's the rest of the fit?

Thanks for the responses. I am pretty happy with the rest of the fit. I am messing with the saddle fore/aft position, trying to relieve a little discomfort in my hands. I think from too much weight on them. I will also try lowering the saddle a few mm, as suggested.

I went to a lbs last night, and bought the Romin Evo in 143mm. Going to give it a shot. I just couldn't imagine going even wider than the Flite at 150mm.

I use the same saddle and am of two minds about it. It may the widest saddle I ever put on a road bike. When honking, I do feel like I need to perch forward on it a bit so the flare isn't mashing my glutes. Sitting up, climbing, or hands raised in victory, the width feels just right.

I think all you can do is try different saddles, find out things that work and don't work about particular saddles and narrow down the s. earch.

I've been riding a 143mm toupe. sit bones are fine but get chafing where my bottom meets the thighs from rubbing over the saddle where it flares out. Did go through a retul fit so assume the saddle height is close.

I just put a cobb saddle on the other day and spun for 15 min on the trainer. Although it's narrower is still seems to support sit bones fine and the lack of a sudden flare out at the rear may help but this model "v flow max" is too wide in the nose for me I think. need more ride time.

Has anyone else had experience with Cobb saddles? They also seem kind of heavy, but comfort may have to trump that.

I find that i also tend to perch forward on the Flite Max. Hence the thinking that a narrower saddle may fit the bill.

Your sit bones are only 110 mm apart, you should get a saddle that's only 131 mm wide. A wider saddle might not be a better fit especially if your sit bones end up right at the edges of the cutout. If your saddle fits you perfectly it will sort of disappear from your conscious thoughts while riding.

Just so you have something to compare, my sit bones are 130 mm apart and my Selle Italia Superflow is 143 mm wide. That means my sit bones are only 6.5 mm from the outside edges. But the saddle fits me perfectly while riding.

I always thought I had wide sit bones because of needing the Terry Falcon Y (men's) saddle with 140 mm width. Never measured the sit bones. I am surprised to hear from so many men (yes?) riding even wider saddles as I always felt they were rather hard to find. In my experience most saddles offered for racing are about 127 mm wide. Am I missing something? Having said all that, the Terry is the best, most comfortable saddle I have ever ridden. The narrower saddles were extremely painful "between the sit bones".
