Road saddles are tricky to buy online. This is the 5th one I’ve purchased and while not ideal, it’s a very good saddle. I’m 6’-1” with 33” waist, 170 lbs and I’m in my early 60s. I had a Fizik saddle I rode on for 10 yrs. Loved the fit, but wanted one with an open channel to reduce nerve compression. (As you get older nerve compression from cycling can reduce sensation of your other leg!). To me, this saddle is a little short as I’d prefer 1” or 1.5” longer with an extended open channel. Selle has some longer models so may eventually try one. I had a hard time finding a seat to fit curvature of my butt/bones. Tried 2 ISM saddles and loved their open channels and pronged open front, but the 2 that I tried were too flat on top which caused the rounded edges sloping downward to be uncomfortable. The Selle Italia saddles are classic curvature for road cycling and there are different models to pick from. This was the 3rd one I tried from Selle and it fits me best for road cycling. Sleek comfortable contour and lightweight with adequate padding. Texture of surface is a bit grippy - would be better with a faux leather or something that allows more sliding, but then again, this saddle has slight curvature to it’s shape so you are fit into it; for some riders this might limit how much you can move to the back. On long climbs , for example, this might be an issue for some riders that like to sit back on the saddle going up a long grade. I compensated for the lack of length but lowering the front by 2 or 3 degrees and on 25 mile ride today had no discomfort or compression of soft tissue. It’s a tighter fitting saddle than I’m used to but seems to work very well and open channel does seem to relieve my never compression issue. For most road cyclists this is probably a very good choice so long as it fits your body.

Delivery was fast. Well made, does not creak. If it fits your body you probably will love it. I was surprised how short it is but as it turns out when I sit in the "sweet spot" in this saddle support is great, pressure where its supposed to be, does not hurt after my usual 1 to 2 hour rides. Cut out is well positioned and helps me enjoy the ride. Padding is fine not too thin or thick. Looking forward to longer rides to really test the comfort level. Expensive? If it helps make cycling more enjoyable its worth every penny.

I bought a new Trek Domane AL5. The saddle was pretty good, but I would get sit bone pains after long rides. A lot of riders I know swear by this and I see why! It takes a good bike fit to really work out exact positioning, but after a couple tweaks on the pitch, fore and aft positioning, and saddle height, I love it. I have ridden 3000 miles on this saddle including several 50-80 miles rides and I am very happy with this. I think unless you are very short or have a really narrow skeletal structure the 135mm should fit most adults just fine. Some people think they need a bigger saddle because they have a larger waist. But your sit bones are still the same no matter how big your waist is.

This saddle is good for people who have there left and right balanced, for me my right sit bone is slightly higher than my left, this saddle makes the power transfer uneven making me more left dominant. So this saddle is not for me. I wish the rail length was a little longer as the other Selle Italia boost. Overall, I believe this saddle is a good endurance saddle. I did not feel pain over long rides.

I've put 200 miles on this saddle now, with the longest single ride being 65 miles. It's incredibly comfortable and I see why it's such a popular saddle. First of all, the center cut-out is a game changer. I was experience numbness on my old saddle (though it wasn't always that way; the problem developed this season), so going to the cut-out sadle IMMEDIATELY solved this. ZERO numbness. The saddle has very little padding, but it's surprisingly well suited to endurance riding (I have it mounted on my Canyon Endurace CF SL). It took about 50 miles to break in, but since then I don't even feel the thing. Perhaps after the 60 miles mark on my rides I start becoming "aware" of the contact points on the saddle, but it's minimal.. and that's pretty normal for any saddle after awhile. Still, for being such a short and compact shape, I find a surprising amount of positions on it. As advertsized, you can really ride comfortably on the nose of this thing and put the power down. Highly recommended. Just get it. FYI: I have 110mm sit bones and bout the S3 (130mm wide) version. Perfect fit.

I set up and road on a trainer for 30 odd minutes which is all I could take. It's hard, short, and despite the reviews of decreased perineal pressure and relief from a numb penis, I experienced more pain and suffering with this saddle than I have with the old Flite saddle (now Flite 1990) that I've been riding on since the 90's. back it goes. Going to try the endurance novus version of this one next, and if that sucks, back to the old Flite.

Recommended by chatgpt after telling it the problems I was having. Took care of all my issues. But every person is different and needs a different saddle. But for me I can ride for hours with no issues.
