Slightly narrower in the nose than the old PRO Stealth. This curved version has a more pronounced curve side-to-side and front-to-back. Side-to-side curve helps with less fatigue in the inner groin area, front-to-back curve supports you more when you are deep in the drops because you have something to press your bum against while hammering. Overall, it definitely feels more comfortable to me compared to the old PRO Stealth, which was already a very comfortable saddle for me. Be careful while setting it up due to the front-to-back curve. You want the front half of the saddle parallel to the ground.
Been a fan of the Pro Stealth since it was first launched a few years back. Thought I would give the newest iteration a try. Honestly can't say I feel any major difference between this model and its predecessor, although they claim this model is more suited to "hip rockers." All around great saddle.
Like many riders, been in a constant search for that "perfect" saddle to feel right. Experimented with over 30+ saddles over the many years and when I tried this Pro Stealth Curved....I felt like I finally found something that works, feels good, is lightweight, and keeps me from numbness in the Nether-regions and also doesn't create tingling in my legs after 20 min of riding due to pressure on inner thighs. PRO has quality construction, nice supportive padding w/o being too firm like Fizik, and looks cool. Round rails have a nice amount of fore-aft adjustment and are plenty strong. Saddle nose still has enough length to move forward comfortably on for steep climbs. I set saddle nose level so tail swoops upward and then I have something to push against. After first ride, I did detect slight movement in shell nose on rail, but it has not worsened or made any noises so far after hundreds of MTB miles. In fact, I like saddle so much, I bought another for my CX bike.
I found Pro Stealth model to be comfortable on the nose, but not as much on the tail bones. The curved fixed that issue. So far this is the most comfortable saddle I've ever used. I feel comfortable on Specialized Power saddles for about 1.5 hrs. then it turns into a torture. Stealth curved give me a long lasting comfort.
