The OPTIMA S shares the sleek, low-profile silhouette of our MODUS saddle, built around Reactive Padding™ 2.0.
A shorter nose than other Optima Ti models and a flatter profile across the top let you change position without fighting the saddle. At 240mm long, 145mm wide and 250g, it is light without giving anything up in support.
Our founder designed Zeta's padding around the two things a pressure mat can actually measure: how hard a saddle loads your sit bones, and how hard it presses in the perineal zone between them. Contact pressure, friction and the ground reaction forces travelling up through the bike all build over the course of a ride — and most saddles answer that by adding foam, which compresses and stops helping.
In April 2024, nine saddles were measured on a gebioMized pressure mat by an independent engineer and a professional bike fitter. A Zeta model recorded the lowest peak pressure in each of the two zones measured, and no conventional saddle in the test was lower in both. Every number is published.
Designed by a doctor and avid cyclist, Zeta Saddles patented Reactive Padding™

from 121 reviewsThis saddle fits me perfectly!!
Love it!!
This saddle really does provide great support when climbing seated yet gives lots of freedom of movement in technical terrain.
I ordered a pre-owned seat on a Monday, I had the seat by Thursday and when I opened the box there was a note stating that they weren’t satisfied with the condition of the pre-owned seats in stock so they sent a BRAND new one instead! 10/10
I have tried so many saddles in my life but none better than this Zeta! No matter how long the ride I forget I’m even sitting. No pain just FUN!
This is the best seat I own. This purchase made Number 5 for my 5th new bike.
Have 5 of these seats and they are great along with fantastic customer service!!
Bought the 2nd saddle so I don’t have to switch it out for my rainy day bike. Thinking about getting a 3rd one for the gravel bike.
Very comfortable saddle for gravel bike. it provides great support for riders requiring wider saddles.
I've struggled with saddle discomfort on longer rides and tried a few different saddles. I know saddle choice is very personal but I can say this one worked for me. I decided to go all in and ride it for the first time at Unbound 100 and for the first time I had no discomfort on a long ride. Definitely recommend!
Very comfortable saddle... Couldn't sit on the one I had it hurt too much. As good as a shaped piece of wood wrapped in leather.
The Optima is just the opposite I don't even think about it. Now I enjoy the rides and absolutely recommend the Zeta Optima.
I have been a life long cyclist. I have a box full of seats in my garage. None of them are comfortable. I tried the Zeta on a whim and immediately fell in love with it. I mounted it on my Pinarello X7. It is a marriage made in heaven. I will be ordering another for my second bike. Marc F.
I have bought 5 Zeta Saddles...one for all my bikes and a spare. I can ride 4 hours with no pain with the Zeta saddles...Excellent product
Awesome seat! I like this seat so much I purchased 1 for each of my 4 road bikes.
I have gone through multiple saddles looking for one that didn't make my sits bones ache and my crotch go numb after 30 minutes. I finally found it!. I was hesitant to try it after all the other disappointments but it paid off. Great product.
I have tried many many saddles. Zeta saddles finally get me pain free on my longest rides. I have three of their saddles, one fir each of my bikes.
