Selle SMP Trk - What Size and Anyone Got One??

I had my sit bones measured and they came out at 143mm ... I'm thinking about getting a Selle SMP TRK does anyone know if I'd most likely be best off with the medium or large both linked below and one's 160mm the other 177mm

Also interested to hear from anyone else that's got one and what your thoughts are on them?

Short story: With a saddle with that much padding, it doesn't matter where your sit bones line up. The padding will compensate. SMP sells that saddle to meet a certain clientele but it is in no way their target market. They were in the forefront of developing serious road bike saddles including introducing the slot in the middle of the saddle. I have a SMP Dynamic and after reading extensively about not only the theory behind it's development but how to set it up properly on the bike, it took a month of fiddling with fore/aft and forward tilt to get it right. I rode seventy miles last week nonstop and the saddle didn't even come to mind. It's just my opinion but you don't have to pay the top dollar SMP's command for an overly padded saddle that you can buy at any LBS for a fraction of the price.

IMO, where your bones line up does matter with a TRK, and with every other saddle. The thing is, the critical width IMO is between the pubic rami, which get narrower as they approach the pubic bone. My experience is probably different from yours, but most of my weight is carried toward the front the the TRK, and I like the padding there, though I don't like the padding at the back.

Do you ride leaning forward or upright? The more upright, the more weight you'll put on the back of a saddle. Why Selle SMP? I went to it to prevent perineal numbness.

143 mm for sit-bone width is pretty large. How tall are you? How did you measure your width? Per Cervelo (https://www.cervelo.com/en/engineeri...f-road-saddles), we need 10 mm outside of the ischial tuberosities on each side, so if you measured correctly, you need a seat 163 mm wide, much closer to the 'medium' than the 'large.'

All SMP saddles, regardless of padding are designed so that there is only one spot to sit. That being at the bottom of the trough of the saddle. The degree of saddle tilt (usually between 0 and 5 degrees down) relieves pressure on the soft tissue. Sitting anywhere else on the SMP saddle other than in the trough is using the saddle outside the design parameters of the manufacture.

IIRC my sit bones are about 143mm also. I recently went through the new saddle buying ordeal ( what a PITA ). I tested several out, luckily my LBS had a program where you pay $25 and you can try basically any saddle they have, and when you finally decide the $25 goes to the sale. I tried a few Fabric’s and liked one in particular, but it didn’t have the cutout relief, and i could defintely feel it ( like a 20 mile prostate exam that day! ). I even got to try the Infinity Saddle. Wow. More power to those that ride one of those. That damn thing poked me in places that should never be poked!! Anyway, the point of all of this is, i had finally tried the SMP TRK medium. I could instantly tell it was comfortable. The proof was after riding it. I did a few 20 mile rides and had no issues, so i was sold. Since then I did my first 45mile ride, NO issues whatsoever with comfort. After that ride i did my first metric Century and it was comfortable the whole time. It’s not as sleek as most saddles out there, so if you have an agressive riding style, it might not be for you. But I don’t ride in the drops very often, so it’s perfect for me.

I think the Medium is the one you should go with.

I probably lean at a moderate level although it's on a 29er not a road bike. I chose this both to prevent perineal numbness but also thought I'd try a different saddle as my hip which has been replaced started playing up recently.

I'm 5'7 and my sit bones were measured in a shop on one of the ass-o-meter's, he seemed to think there should be 25mm added so 168 and the TRK falls between the 2 ... if I look at their size guide based on waist size again I fall between the 2.

I tried looking at the link but it just took me to a ho,e page for some reason, I googled as well and couldn't find it either.

True. If you're referring to my comment about where my weight is carried, I don't think there's any contradiction. I lean forward to reach my 'bars, so my weight is centered forward, and I stay in one place. Besides, design is one thing; use is another.

I went to the TRK from a Brooks B17 Imperial. I tend not to like padding in my bike saddle or bike shorts. But I had perineal numbness with the Brooks, not with the TRK. At my age, I want the blood to flow in that area. I tried a Selle SMP Blaster for a couple of hundred miles in September. It didn't work - I got numb if I sat per the design. It's longer from the trough to the highest part than the TRK.

It looks like the link is dead. Sorry. In any case, my memory is pretty clear that they recomend getting a seat that's 20 mm wider than sit-bone width.

I gather that the medium is supposed to be the man's version and the large is the lady's. The wider one is a cm shorter and some places sell them as "man" and "lady"

Those pages aren't available outside the US unfortunately but I'll google and see what I can find.

I appreciate they're a different company but the 2nd paragraph of this article is interest from the point of what would be considered small, medium or large and would have thought different manufacturers have similar parameters in which case I would be a large unless as you say it's just the difference between men and women's saddles
