I love that is comes in a wider 155mm width unlike almost every other brand. Only the heavy steel railed model is available, so I had to hunt for a used carbon railed Sitero for my other bike. . . yes it's so good I bought it twice.

Been on a few saddles over the years and realized this full channel that moves all the way to front is what is needed. Bought 1 and now buying 2 more!

The main reason for me to get this saddle was genital numbness in prolonged aero position. This saddle 100% addressed that. In my road bike I have the 143mm power comp saddle, but that size isn’t available for this model. I tried the 130 and 155 and the 155 was too big. The 130 is great in aero position, but in a more seated position my bones are not resting flat, so gets a bit uncomfortable after a bit. If this model had a 143mm size, this would be perfection!

Best saddle I’ve found for the aero position, and I’ve tried several. The regular Sitero was good, but the 130 size fits my narrow hips better and so is more comfortable. Going fast is easier if you’re not experiencing any saddle discomfort, just concentrate on putting down the power.

Seems ok. Sits atop my turbo trainer. I'd recommend

I have road bicycle with added aero bars which made the original saddle uncomfortable in aero position. This saddle is much better since it’s designed exactly for that. I can stay much longer in aero position with better comfort. It takes some time getting used to and I think it’s a little too wide at the tip, but that probably an individual preference. I ride for triathlons. Had it installed for about a month and rode well over 200 miles including 50 in single rides. So far so good!

A well made saddle, but unfortunately not the best for me. Specialized refunded with no problem within the 30 day promise.

I am now at 2000+ miles with this saddle on my road bike. Best saddle I have owned! Comfortable, very comfortable! I was always looking for other options but today I just enjoy the ride. I am happy that I decided to try this one, and you should too. Seriously.

I wasn't sure what to expect as I had previously tried the ISM Adamo saddle and it was too wide at the nose and caused me to have painful inner thighs. I got the 155mm Sitero level 3 padding saddle and after a couple of rides, it now feels absolutely fine and is very comfortable even when in the TT position for long sections at a time.

I wanted to try this saddle as my full-time Road Saddle. As I grow older it becomes hard to find real comfort, especially on longer rides. This saddle is pretty close, and I expect it to get better as it breaks-in more. Yes, it feels different since the nose is twice as wide as the Power Elaston. The pressure points are different, but on the drops or up on the hoods this one works well for me. I am now looking forward to extending my miles this summer. Give it a try!
