Read more in this forum from the mechanics section. Even if it doesnt interest you just read it and learn. Then from there you can learn to adjust/assemble your own bike. Or go to the park web site. its very easy to understand and in-depth. You will find that most basics repairs you can do yourself. There is no nead to pay to get it done. And im a bike mechanic saying this, I hate to say that shops are useless with basic stuff, but its the truth. Dont be intimidated by your bike, just learn about the parts on it and how to adjust/fix them. It will make you a better rider, in my opinion. It takes time but its worth it.
