Can you lower a seat post too far?
Long story short - I believe I was put into the wrong size by a shop salesperson. I'm 5'9"-5'10" and went assuming I'd be a 54cm. He ultimately talked me into a 56cm and said that as an "older" person it would give me a more upright position. I'm 37. I rode a bunch and could never get comfortable so I started going down the rabbit hole of fitting. I quickly realized the seat post is way too high, and lowering it makes me way more comfortable. However, it appears that there are etched in markings for going too high and too low on the seat post. What is the danger of too low? I need it slightly lower than were the marking is. Bike is a Specialized Allez. The salesperson also is the one that set the seat post height for me. I am in talks with the manager to see if they can help me, but can't return for another size.
