Hi there, from my side I did not recommend this frame. I had problems with slack on headset (too short bearrings). You are not able to proper mount front derailleur mechanic ultegra r8000 because it's rubbing against own cable armor and can not change for little gear  . cracking carbon around saddle post. There is no EPS moulding and from I read on forum there are better frames in that price.

So my social feeds urged me to try out Selle SMP saddles for a while.
I've been curious and more or less on a whim I bought the Velobuild replica of what I believe is the Selle SMP Dynamic saddle. It's their long standing classic. I was expecting this to be an instrument of torture. And while I still have to ride this for more than 2 hours straight, I'm really surprised as to how comfy this is. Once you have it dialed in, it kind of feels like you're sitting on something that basically perfectly fits your pelvis. I had to set this way further forward than my previous saddle because it basically has to disappear under your bum. You can't sit on the nose of this thing. There's pretty much exactly one spot only where this saddle feels comfy. But once you've found it, you're locked in position and you basically rotate your pelvis back and forth while sitting on the same part of the saddle depending on how aggressive you wanna ride. You do not move back or forth on this saddle at all. No sliding towards the nose and having to readjust your bum when tucking down. I'm very intrigued.
You do however have to live with the way it looks. Th e best thing about the design of this saddle is that most of the time you're sitting on it.

@Sebastian, can you give more details about this saddle? How wide is it 130mm or about 140mm? How much foam is there? How about wearing a material after some that time? Can you upload photo from the top?
I am asking, beacuse I was using Selle Italia slr superflow slr L3 (143mm) on endurace bike and it was perfect, but after switching to aero bike with more aggressive position I started to produce sore between butt and leg throught which i had two months of the season off my bike.
My hypothesis is that after switching I started rubbing with bibs in the sore area that is why I am trying to find more narrow saddle with slender expansion on the ischium.
Next week I will try to borrow Selle Italia slr superflow slr S3 (130mm) and test it, unfortunately it is hard to find SMP saddles to borrow.
