Description

Support you can count on.

Addressing pressure at the perineum region is what the Dynamic saddle does best, as it relies on Selle SMP's innovative shape to keep you comfortable, pressure-free, and supported while out on your bike.

Like the all-rounder Lite 209 and Stratos, the Dynamic is best suited for cyclists with average-width pelvises, as it features a moderate profile and a fairly minimal amount of padding. At the nose, there's the characteristic "beak" shape designed to provide a flat base while sitting, without excessive pressure on the genital area. SMP's pronounced central channel was also incorporated, which further reduces pressure on the pudendal nerve and surrounding soft tissue. The back of the saddle is raised for an enhanced seated pedaling position, where body weight is divided between the rear and lower part of the ischial tuberosity region. This shape also helps reduce overall pressure on the coccyx while riding over rough surfaces.

The saddle's foam elastomer padding gets wrapped in leather for the black version and a durable Lorica microfiber in the colored version. Its durable nylon/carbon composite shell rides on stainless steel rails, ensuring a secure perch that'll hold up for both road and mountain applications.

The Selle SMP Dynamic is available in one size (274 x 138mm) and in the colors Black and White. It is handmade in Italy and has a claimed weight of 260 grams.

Happiness all over again!

  • Familiarity: I've put it through the wringer

The quest to find the right saddle that works for each of us is a challenge that none enjoy doing and once that unicorn has been found, it is hard to look again.

This is my unicorn, the one that works well for myself and my son. I have been riding bikes for 25+ years and I feel this is the most comfortable saddle I have ever ridden or raced on. When you sit on this saddle you feel your self sit down inside of it, and not riding on top of a padded shell (like other saddles). Not only does the sitting inside the saddle add comfort, but it also makes me feel more in-tune with the bike and what is going on. To make sure I wasn't imagining things, I went back to another saddle I have like on another bike, and there isn't any comparison between that saddle and this SMP Dynamic! The leather is top notch, the rails are replaceable, and the padding is just enough for me (a great pair of shorts is a must).

As time goes, I will need to pick up a few more and keep them in the ready for when it's time to replace.

If you have questions about SMP saddles or others, please reach out.

Happiness all over again!

The Love Fest Continues

  • Familiarity: I've put it through the wringer

First thing I will say is that a saddle is a very personal preference, I have friends that ride saddles that I cannot stand and I am sure I have liked saddles that other do not.
Second thing I will say, is aside from the initial investment of the correctly sized bike, and some good quality shorts. A bicycle fit should be high on your list, not some “free bike fit” but an actual fit performed by somebody that knows what they are doing with certifications or experience to back it up. A good fit will take a few hours and usually starts with a lot of questions.

I love this saddle! I would say it took 3-4 rides of adjusting the angle of it before I felt like it was dialed for me, starting relatively flat and then angling the nose downward until I hit the sweet spot. I feel like this is important since it is not like any other saddle out there, setup isn’t quite as straight forward but you will be rewarded for your patience. The Dynamic resides on the firmer end of the Selle SMP spectrum but is actually a touch softer than what I have liked in the past. Also these saddles are not as width focused as other companies, which I was skeptical about until I got some miles on it. Make no mistake, I think it is a wonky looking saddle and it is not going to win any weight wars as it is nowhere near as light as the carbon saddle that it has permanently replaced. It makes up for any shortcomings with the fact that it just works, I am not getting saddle sores, I am not finding any discomfort, and I am not having numbness issues. So unconventional looks be damned, I am sold.
Build quality is the best I have seen, no creaking, no shoddy workmanship, just top quality construction and materials. Did an 8+ hour gravel ride on this with zero comfort issues.
This is my saddle.

I have owned and spent time on numerous saddles from Selle Italia, Fabric, WTB, Specialized, Bontrager, Fizik, ISM and Terry (I was trying everything I could at one point)

My 1 star review may seem unnecessarily harsh. It is a high quality saddle but if flat across the back works for you proceed with caution. The lower your position the more effective width you need.

The perfect girlfriend

  • Familiarity: I've put it through the wringer

Sorry to rain on the love fest but, for me it was like that perfect girlfriend that I couldn't live with 24/7. After 6-8 happy years WTB discontinued the Devo which put me in the market for a new saddle.

I have multiple friends that ride SMPs and everyone loves them. I got a chance to do short rides on the Composit and the Dynamic. When I found a 20% coupon I stuck a crowbar in my wallet and bought a Dynamic which with thin padding seemed the safer choice than the unpadded Compsit. This was early last year I did a couple of rides in Feb before a ski vacation and got serious about set up in March. During this time I kept the Devo on one bike and was constantly back and forth. It took a couple of months, but we finally came to terms. By the time June rolled around I was riding about 200 miles a week and it became my preferred saddle. For the first hour I was aware that the padding was thin, but shape seemed to work and 3 hours later it seemed to disappear.

July rolls around and I jumped at the chance to pick up a used clean one owner model for the second bike.

This is where things quickly went south. My serious riding started before LeMond made his comeback and in almost 30 years I could count the saddle sores I've had on one hand. But boom a week later I have one and I can't get rid of one before another pops up. Alcohol, chamois cream, antibacterial cream, hydrocortisone, changing immediately after riding; nothing helps. Sometime in August I hit up the Doc for some triamcinolone cream (choice of champions) and expected miracles. It barely made a difference and next month I'm asking for the stronger version and I still can't get rid of one before another takes its place. Finally in October I gave up and pulled off the SMPs and experienced sweet relief.

So what went wrong? The dynamic has significantly less effective width and the rear of the saddle just didn't carry it's share of the load.

Before you even consider an SMP google Steve Hogg SMP. Read it, think about it, and repeat several times. You'll learn things you never knew existed. They do distribute weight fore/aft but for me the critical thing seemed to be effective width which is determined by how flat the saddle is side to side. I'm not sure exactly what his methodology is , but I got good correlation using the highly scientific method of laying a flat stick across the wide part of the seat and sliding a .25" shim in from the sides until they touched and measuring between them. The devo had ~30 mm extra effective width. The extra effective width means more weight is carried on the rear of the saddle. Without enough effective width to support your sit bones the rear of the saddle doesn't carry it's share and all of your weight is on the 2 narrow strips on either side of the cut out. All the other saddles in the garage that I can tolerate are also effectively wider. Where maximum effective width occurs and the taper rate can vary widely between saddles. The width in the nose is not much different, but the taper is a straight line that never flares. By the time it gets back to the sit bones the score is: Devo 128, Dynamic 96.

I tried one more time in November and 7 hours riding in 2 days was enough to give me another sore. I rode almost 8k miles last year probably half on the SMP Dynamic so if you have comments that I just need $300 shorts, or that I'll get used to it, or it needs one more adjustment, please keep them to yourself.

In hindsight the wider effective width of the Composit would probably work better for me, but I'm not going to spend the money to find out. The weird thing is unlike girlfriends even in hindsight I didn't see the problem coming.

The picture illustrates the effective width difference between the Devo and the Dynamic. The distance between shims is the effective width of the Devo. The total width difference is only about 5mm.

The perfect girlfriend

Awesome review. Much appreciated. You saved me from a very expensive - and painful - experiment.

It's the go to!

  • Familiarity: I've put it through the wringer

Took a long time to try this saddle due to the price, wish I would have tried it first! Yes it's goofy looking, but hands down has the most contact of any saddle I've tried. Meaning more contact = distribution of weight on you nether soft tissues = more time riding without irritation.

I've found it works great tilted 5* nose down.

Comfort

  • Familiarity: I've put it through the wringer

This is the second one I own. It is instantly comfortable and not binding in areas that other saddles grab you. I love the freedom to move around on long rides and still feel comfortable.

Test ride.

  • Familiarity: I've used it once or twice and have initial impressions

I test rode this saddle and the SMP 209. Bought the 209. But I wish I had tried this one longer. My impressions of the SMP line of saddles:

First, gentlemen, it is really important to protect the soft tissues around the perineum while riding 2-3 (or more) hours in the saddle. Urological problems can develop (ouch!) if the perineal area (including the pudental nerve) is compressed for long periods of time; especially if you ride in an aggressive forward position. Hence, the Selle SMP line of saddles.

That said, saddle choice is extremely personal. Variables such as specific physiology (sit bone width), position on the bike, fitness level, and BMI result in... no size/model works best for everyone.

So, SMP makes a lot of models. Check out the SMP website (or google Steve Hogg) for fit and correct model info. It seems the "Dynamic" or the "Lite 209" (inexplicable name) are the models to buy for most fit male riders of average pelvis width.

100% hand made in Italy (and beautifully so), real leather (in black).

*Important note: Setting up this saddle properly on your bike (usually nose down 2-5%) is essential to this saddle working properly. So check out the SMP website (or google Steve Hogg fitting) for proper set-up advice.

Did you try the Drakon model ? Its right in the middle between the Dynamic and the 209, perhaps a happy medium
