I have found the EC90 saddles to be more comfortable than the older fully padded ones. The problem here is that they had 7 x 9 mm oval saddle rails. The size of the steel and aluminum bike seat posts are liable to be all sorts of weirdo sizes and the only seat posts that purposely allow the 7 x 9 are the newer carbon posts with a diameter of 27.2, 30.9 and 32.8 To fit, say, a 26.8 mm seat post with the oval rails, would require, at the very least, buying a new screw that would allow the top connector to lift up higher.

Now, there are full carbon saddles available with titanium rails or probably even steel but I don't expect them to be available for a lot longer since the full carbon rails are so much lighter (well twice feather light is hardly heavy)/ Once they are fully set up to make carbon fiber saddle rails that is what will take over since the material is so much cheaper than metal.

I have ridden at least four different shapes of these thin carbon fiber saddles and in every case I have had less butt aches than with any of the padded saddles so I do expect them to completely take over.

Tom, get a Thomson seatpost, the aluminum version. US made and it will accep 7*9 mm saddle rails. I’m a fan of Thomson seatposts.

I am as well but they are something like $110. And the first thing you do is buy extra-long screws for the deep rails.
