Subject: Educate me on Seat posts I am in need or a new seat post for my road bike. I picked up a new saddle with a typical two rail setup which is different than the one I currently have. So here are my questions accepting that I don't know what I don't know:
1. The seat post on the bike now is 31.6 mm. But I see the lengths differ quite a bit. How do you decide on the proper length?
2. Some seat posts say they are for a mountain bike. What is the difference between two different models the same size if one is for a mountain bike and one for a road bike?
3. I see prices all over the place. What is worth paying for and what is not?
4. What didn't I ask that I should have?
Thanks in advance.
