I've been struggling with pudendal neuralgia for years, and I got the the power comp with mimic which definitely helped. It was still a bit hard though, and the flatness of the surface felt like it put pressure on the area inside my sits bones that was causing the pain and itching. The power arc with elaston solves both of those issues, and feels supportive yet squishy in all of the right places. The added padding alone the sides of the nose and middle is especially helpful. My symptoms have been much better since I began riding with it. The curved nature of the back fits into my pelvis better, and feels like it's a part of me rather than something I'm perched on top of. My bike fit guy told me that this is what he rides, and I see why! If you are a fan of the power platform but want a better version of the saddle, this is it!

I had tired a few saddles, and I settled on this one!

This is my first new saddle in many, many years. Like everything else these days, it's amazing how the technology has changed. Everything from the shape to the cutout to the Elaston padding make for a saddle that is immediately comfortable. I'm sure it will become even more so as I rack up the miles. Thanks for a great product, Specialized!

The channel is NOT the same width as the original. In fact, the channel on the Arc Elaston Pro 143 and 155 is significantly narrower than on the Power Pro's. Also, the padding on the front of the Power Pro Elaston seems much softer than on the Arc Elaston models. "our original Power saddle. It features the same channel and length as the original"

This page claims that this Arc saddle has the "same channel as the original" (Power Pro), however, this is not the case. 1. Most importantly, the Arc has a significantly narrower channel, almost 10 mm narrower. 2. Also, the front part of the Arc Pro Elaston is firmer than the Power Pro Elaston. 3. In addition, I can confirm the Power Pro 155 has a wider channel than the Power Pro Elaston 143. 4. Lastly, the Arc Pro Elaston143 has a channel that is, I am told, the same width as the Arc Pro Elaston 155. 5. The channels on the Power Pro and Arc Pro saddles have different widths. So, in case an exchange is needed, keep all the packaging and test the saddle immediately after purchasing it.
