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.

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 girl who was perfect 2 days a week that I couldn't live everyday.
I had been happy on the WTB devo until it was discontinued.
I know a lot of people who swear by the SMP and I got a chance to do short rides on both the composit and dynamic. I ride 2 bikes and in February I put a dynamic on one. I alternated as I tweaked the set up of the SMP. It took time to come to terms with it but by April it had become my preferred seat for long rides. For the first hour I was aware that it didn't have much padding, but 3 hours later I'd find that the shape worked and the lack of padding didn't matter. In late June I got a chance to get a good used one and set up both bikes the same. At this point I was riding about 200 miles per week and a funny thing happened. After having only a handful of saddle sores since the days of LeMond they became chronic. Finally in August I hit the doctor up for some triamcinolone cream and expected them to disappear. Before one would heal there was always another to take it's place. October rolled around and I got the doc to give me the higher concentration which helped, but They didn't disappear until I quit riding the SMP. But like an old flame I couldn't stay away and went back for another try. 2 days and 2 3-4 hour rides later bam another sore popped up. By this time it was late November and I had spent 3-4k miles on the SMP. I also moved on to a Fabric scoop as a second saddle which shares a common characteristic with the devo: They are both relatively wide and flat side to side across the back.
So what went wrong? The dynamic is slightly narrower and rolls off more side to side which makes it effectively even more narrow and puts all of pressure on narrow strips next to the cut out. I average over 7k miles a year and wanted to love it but I just couldn't tolerate the saddle sores. But just like a hot girlfriend I still have one set up on a spare seat post in case I decide to blow on the embers one more time.
Read Steve Hoggs website for more info than I can possibly give you. The irony is that the dynamic with padding seemed to be a safer choice, but in hindsight the wider effective width of the composit may have worked better for me.

It's the go to!

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.

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
