I just bought my first mountain bike! I bought a '05 Cannondale F300 on sale at a LBS. I decided to just buy a low-end mountain bike since I don't really care if the bike is heavy and i don't care if the gear skips a little. Gears can skip a lot in high-end components too as I've experienced it with my all dura-ace road bike. Anyways, I didn't see a need for an expensive bike and I would look like a tool having a nice mountain bike and i'm just a beginner.
I'm 5'9" and I have a 30 inch inseam so I bought a size medium. I guess from my road biking background, I prefer to have my seat pretty high since I feel more comfortable with it. I feel like too much of my seatpost is exposed as I think about 2/3 to 3/4 of the seatpost is exposed. It seems like that is too much. There is not a max. point marked on the seatpost so I don't know if it's too much. Do you think there's a good chance it'll snap? I might take it over to the bikeshop when I have this week to ask them about it, but any input from you guys will help.
