Hey all. Need a little direction on a new seat post. I bought a used Selle SMP Dynamic saddle in super nice condition. Upon fitting it to the existing post I see that I'm going to need a new post. I need to raise the nose of the saddle just a bit, but I'm at the very end on my adjustments on the existing post. It's a 20+ year-old "Skye" post that came with the bike (a BikeDirect "Motobecane Record".) So, what's a recommended post that comes with a large angle of micro adjustments? I prefer an aluminum post, but will jump for a carbon post if the price isn't crazy.

Also, I measured the diameter of the existing post and it's 25mm. In researching, I see the smallest diameter on modern posts appears to be 25.4mm. Will I need to get a shim of some sort, or will a 24.5 work? Again, I estimate the frame to be at least 20 years old.

Thanks all!
