OUR CUSTOMERS SAY IT BEST...
A NEW ZETA FOR AN 8 HOUR RIDE?
"I bought a Zeta because I have had a LOT of pain during long MTB efforts (particularly races over 35 miles).
I put it on for an 8 hr race last month and it helped significantly.
After doing shorter rides on another bike (not equipped with a Zeta saddle) I realized even more how much I liked it.
Looks like I will be buying a couple more for my other bikes.
Reasonably priced and well worth the small weight penalty."

HOW ZETA'S REACTIVE PADDING™ CUSHIONS THE RIDER ANATOMY
Traditional foam: Compresses flat. Stays compressed. Forces go straight through.
Reactive Padding™: Adapts in real time—shifting, cushioning, and redistributing forces exactly where you need it most.
Firmer zones cradle your sit bones for stable power transfer.
Softer zones relieve pressure around sensitive areas.
Dynamic core actively absorbs impact before it reaches your body.
Every bump softened. Every vibration dampened. Every pedal stroke balanced.
Settle into a ZETA Saddle and you'll notice it immediately—subtle contouring as Reactive Padding™ adapts to your shape.
As you move, shift, or climb, the support moves with you. Pressure points disappear.
You ride longer. Push harder. Recover faster.
And most importantly? You stop thinking about your saddle at all.

Let customers speak for us
I have tried several saddles but have found the Zeta saddles are the most comfortable especially on longer distance rides. The padding system they developed really works. My wife and I have been replacing our other saddles with Zetas on all our bicycles..
This saddle is comfortable which in turn relieves pressure from my hands.
Pain free riding!
I happened upon Patrick at the El Tour de Tucson Expo. I was riding the Century in a few days and knew my Selle SMP wouldn't be pain free despite having some RedWhite bibs. The Zeta saddles looked interesting, so I gave the Optima 145 Ti a try. I can't say enough about how comfortable the saddle was. I am a slow rider, so the 103 miles took me over 8 hours of ride time. During the ride I barely notice the saddle at all. Every once and awhile it would feel hard - especially on rough roads. But a minor shift in my sitting position and it instantly went away. Most surprising was how I felt at the end of the ride and the next day. Nothing - absolutely nothing! It was if I hadn't ridden in days. No sore spots, chaffing, or tenderness. I have never had this happen on such a long ride. Riding in the days since El Tour de Tucson has reinforced my reaction. This is really a comfortable saddle - and I have already ordered my another one for my second bike.
Getting the saddle to fit took a bit of experimentation. It was very different than my old saddle. To get the full benefits I had to sit farther back on the saddle than I was used to. After moving the saddle forward and tipping the nose up a bit, things felt more natural. The fitting instructions provided with the saddle are spot on.
I also want to thank Patrick who was extremely easy to work with.
I know, saddles are a subjective issue because everyone's bodies and needs are not the same, so I'll throw in my two cents.
I'm a 78 year old rider with a lot of saddle time (40 plus years) under my butt. I have purchased all makes of saddles over the years. Most have worked for a time, but as I age I started feeling uncomfortable cramping and pain in my sit bones, call it old age or whatever, but we all change over time. So when I saw the add for Zeta saddles I was of course skeptical. There was a Holloween special that was offered and the discount made it appealing to try an Optima Ti 145. After 60 miles of riding I must say I am more than pleasantly surprised. So far no cramping or pain . A lot of testing to do but I am optimistic that this saddle is the real deal. The padding under the sit bones is different than anything I have experienced. Cushy but not mushy or overly thick. I went ahead and purchased another. With a money back return policy, it's worth a try for sure.
Nice quality, good price point and after 5 rides approximately 100 miles I am happy to say that the comfort level exceeded my expectations thanks for putting a quality product on the Market.

This saddle takes the edge off of all variety of bumps and roughness.
Thanks again for the ultima and the baseball cap!! I just placed another order I’m on my 3rd one now!!
The ZETA optima resolved sitting issues. Comfortable! Used on a two day shakedown overnighter ride and then a 5 day bikepacking tour in Kentucky. All good for longer trips.
Very comfy saddle! Bought used but the saddle was in like-new condition! Great customer service and fast shipping
Riding on Zwift I find that I sit a lot more than I would on the road. This saddle actually made my long rides less painful, No numbness or soreness at any point
I’ve tried practically every brand of saddle (some more than once), even a couple 3D printed saddles. The Zeta Optima is by far the best fitting, and most comfortable saddle I've tried. Before the Zeta I could only manage 45-60 minutes pain-free; with the Zeta I’m still comfortable after 2+ hours of riding!
The optima is the 6th saddle I've tried in my search for comfort on my bike and it feels like it might be the one. Its the right width for me and the padding is softer than others i've tried while still providing support. Yes, it was pre-owned but it looks brand new.
It's the shape I prefer and is very well-made with just enough cushion. I'm considering getting a second one for my other road bike that has the saddle I love so much it's now held together with duck tape.

REACTIVE PADDING™ INVENTOR AND ZETA FOUNDER DR. PATRICK O’SHEA
As a cyclist, I’ve long been aware of the issues with mass-produced bike saddles causing numbness, post-ride soreness, and damage to the perineal region. Being a Doctor of Chiropractic who specializes in soft tissue injuries and biomechanics, I treat hundreds of cyclists, mountain bikers, triathletes, and spin enthusiasts who suffer from the build-up of adhesive scar tissue, brought on by overuse and altered body mechanics.
One day while treating a cyclist for chronic pain in the sit bones, I explained how the inability of foam saddles to dampen and absorb forces into the body was one of the main contributors to progressive pain and damage in these areas.
I’ll never forget their reaction: “Why hasn’t anyone invented a bike saddle that prevents this?
”I realized in that moment that I’ve always understood the problem but had not considered taking on the challenge myself. And because of my expertise in biophysics and soft tissue injuries (mixed with my love for cycling) I was the perfect person to solve this universal problem once and for all.
It took a long time. But after years of research and hundreds of iterations, I succeeded in my mission to create Zeta’s 7-piece, proprietary Reactive Padding™.
All of our Zeta Saddle’s provide the ultimate level of comfort and safety without sacrificing performance or speed.
Our saddles remain ultra-light and are made of the highest quality while protecting you from the painful ground reaction forces that come with riding.
By ordering your Zeta Saddle now, you’re helping us in our mission to protect riders around the world from pain, soreness, and soft-tissue damage. Thank you for joining us!

ZETA SADDLES ARE DESIGNED AROUND PROPRIETARY
MULTI DENSITY REACTIVE PADDING™
Inventor and lifelong cyclist Dr. Patrick O’Shea has applied his biomechanical and anatomical knowledge with the physics of cycling and plus advanced shock absorbing materials to develop unique zeta saddles. (Patent# 10,464,624_B2).
* ROAD BIKES * MOUNTAIN BIKES * E-BIKES * SPIN BIKES * COMMUTERS
THE Technology Behind The Comfort: REACTIVE PADDING™
Saddle designers and engineers deploy shock absorbing materials to dissipate bump forces. Entry level saddles often use a single layer of inexpensive foam or gels which are highly susceptible to “compression set,” allowing a rider's pelvic sit-bones to sink to the hard saddle base. The result is hard contact pressure. In addition, higher frequency vibrations from uneven surfaces make there way up into the base of the saddle, ultimately creating continuous impact to the pelvic bones, spine and soft tissues. Zeta’s 7-piece dynamic padding composite structure absorbs the bumps and dissipates the forces while eliminating contact with the saddle's rigid base. Like carbon bike frames, Zeta ‘lays-up’ different shapes, thicknesses and densities of proprietary elastomers in each saddle to optimize force dissipation. The dynamic forces a rider feels in the body are reduced, eliminating acute sit bone pain and reducing the fatigue experienced as you ride longer.

Picking Your Zeta Size
Measuring Your Sit Bones: The 2 Cents Method
- Sit on a hard surface
- Use your fingers to find the pointy end of your sit bones
- Slide some coins to those points
- Rise from the seated position
- Measure the rough width
- Add 30-40mm to that width and select the closest larger saddle width
- Here, the measurement is 110mm
- Suggested saddle size is 140mm to 150mm
- When in doubt, pick the wider saddle

Testimonials
"I love my ZETA MODUS saddle!"
"After going through seven road saddles in ten years, I finally found a light weight, high-performance carbon saddle that actually gives me greater comfort and support. I ride even longer and more often without feeling that typical saddle hardness, sit-bone soreness and groin area numbness that occurred during most rides, especially on my longer rides."
"Trail Rides"
"My trail rides are so much more enjoyable now with my ZETA OPTIMA saddle! To say it’s a lot more comfortable is only part of the story. It actually conforms to my body, my pelvic sit bones sink into the padding but, do not bottom out and feel the hard sit-bone pressure felt on all previous saddles. You can feel the shock absorbing padding working as you ride. Love the sleek, low-profile design too!"
"Optima"
"My new OPTIMA saddle by Zeta Saddles is absolutely the most comfortable saddle ever made! I can’t believe how comfortable it is. There’s such a huge difference in comfort level and performance. Zeta’s Reactive Padding™ absorbs all the bumps and vibrations, and doesn’t have that increasing sense of hard contact pressure and discomfort I’m so used to with my previous saddles. 5-Stars! "
-Todd L.
"Optima for Mountain Bike!"
"Wanted to know how your saddle feels. Over the last few weeks, since I put your saddle on my mountain bike, I have been on 15 rides for about 230 miles.
After I put the saddle on, (which was easy, with the open top to the saddle), the moment I sat on the saddle I could feel the comfort. During my rides, (road several mountain bike trails), I noticed the design did help protect tissue in my groin and sit bone. I have had 10 different saddles on various mountain bikes; the Zeta is by far the most comfortable padding and performance with the titanium rails I have ridden on."
-Vance
"First 1000 Miles on Optima 146mm Titanium Rails"
"I have been riding the saddle for 6 weeks now and the numbness problem I was experiencing is well, solved. I was surprised to be honest. I mounted it on my classic Bianchi steel bike and have gone as long as a century riding it. For me, it works. I do ride with a nice bib under my casual pocketed shorts."
-Vance
"Ultima for the Peloton and E-Bike"
"Zeta’s “ULTIMA” saddle is a dream come true! I love riding my Peloton so much more now! I also have an E-bike that I commute on and it’s super easy to switch my Zeta saddle between the two. I have zero discomfort or soreness during or after my multiple spin sessions and e-bike rides each week. Thank you ZETA! "
