Seatpost for SMP Saddle
I currently have a SMP Well saddle and am going to be testing out a Forma or Dynamic soon as well. SMP has some lengthy rules for the seat post you use with their saddles. I can't post a link to the requirements but basically the seat post needs to be symmetrical where it rests on the rails, it's hard to explain. I'm looking for a seat post that would fit their requirements that is a 2 screw design. My current seat post is a single screw design and I can't adjust the angle as detailed as I'd like to. Also, on my ride this morning the seat post screw got loose and my saddle titled down a lot more than I wanted mid ride. Luckily I was on the trainer so it didn't cause a crash or anything. I don't want the same thing to happen in the future though. Please let me know what seat post you'd suggest or what seat post you use if you use a SMP saddle. Thanks

They just want the jaws that clamp onto the rails to clamp directly opposite of each other on the rail. Apparently some don't. As well you need to make certain that the profile of the grove in the clamp for the rails matches the shape and size of the rails. Carbon rails are sometimes a oval cross-section. So a clamp made for round rails will likely damage oval rails.
So it's possible your current seat post might be all you need. Pages 10 - 13 as numbered on the pages or pdf pages 6 and 7 are what I think you are asking/talking about.... https://www.sellesmp.com/pub/media/w...ev_2020_01.pdf |
Yea that's the document I was referring to. My current seat post isn't quite long enough, it says the clamps should be 32mm, mine aren't quite. Also, the main problem with mine is that it's only one screw and I can't do as fine of angle adjustments as I'd like. It's hard to see close up pictures of a lot seat posts I see online so I can't tell if the jaws will clamp directly opposite or not. SMP's are expensive and I don't want to get a seat post that will damage a new saddle. Hopefully some people use them and have had success with certain seat posts.
Thanks Iride for posting the pdf. |
At last I can brag about my 'Arius' seat post, which I've used since 1982 with several saddles, including Selle SMP, with no problems. Here's a photo: https://www.velovilles.com/en/brands...New-Racer.html. It's a(nother) Campagnolo copy.
The name presumably harks back to the Visigoths who ruled Iberia from the withdrawal of Rome until the Muslim conquest and who were followers of Arius, whose ideas were rejected at the Council of Nicea in the year 325. I'm a history buff.... |

Saddles 'should' tilt up slightly. Dead level, if you must, but any downward tilt and you are not having a quality experience, no matter how much you think you are. If I'm kidding myself about the quality of my experience, well, I've ridden about 4,000 miles on my SMPs with virtually none of the numbness that comes from excess pressure on my pubic nerve. I get pretty numb after about 7 miles on my old Avocet, 12 on a Fizik Aliante, 15 on Brooks Imperial. Old dogmas don't apply to Selle SMPs. |
I’ve been happily using an FSA SLK carbon fiber seatpost for my SMP Dynamic…for almost 10 years. The current design appears unchanged from mine, apart from graphics.
The SLK two-bolt head is secure and easy to adjust as the bolts are outboard of the bike centerline, not inline. |

I'm demoing the Forma now which seems to be pretty much the same as the Dynamic but without any padding. I haven't been able to find a setup that has the same cradling feeling I got with the Well. I don't know if it's because of the size difference or lack of padding. Thanks |

Is it the SL-K SB0, I found that on their website, I can't post a link to it.

I played with saddle position years ago and don’t recall how the position below is called within the SMP world; they’re so swoopy. Is “level” determined by the highest points on the saddle? Dunno, but you can see how it looks: https://cimg5.ibsrv.net/gimg/bikefor...ce9011a4d.jpeg |

I’ve only ridden the Dynamic, so cannot say much relative to other SMP saddles, but will say that the Dynamic doesn’t seem so heavily padded that there’s any kind of cradling feeling due to squish. It’s a very firm saddle. I played with saddle position years ago and don’t recall how the position below is called within the SMP world; they’re so swoopy.

I’ve been using the Smp drakon since 2015 and have been using the Thomson seatpost with it.
I try different saddles, but none can compare with the Smp. I have mine set at 13mm nose down. I may try a Dynamic, but this Drakon is so comfortable I’m afraid to try a different one. |

My understanding is the Drakon is basically the same as the Dynamic but with a little more padding. I'm curious if I would find the Drakon more comfortable because right now my Well is more comfortable than the Forma I'm trying. Maybe I'd be more comfortable with the extra padding, hard to tell. Might have to demo both and see. Thanks for the post. |

Do you use a specific Thomson seat post? I was looking at the Thomson Elite which seems like it would work.

Good looking bike chaad
That’s an old pic, and I’ve since moved on to silver bar tape after a years-long struggle trying to keep white bar tape fresh, but other than that, she’s held up well and looks pretty much the same today. |
