I am very new to cycling again. In fact, I have only ridden a bike for 5 minutes in the last 20 years, and that was last night. A friend of mine gave me his old bike and I want to begin riding. I figure I'll get the hang of cycling with this freebee bike and when I know what I want/need, I will buy a new one (next year).
But, I am concerned about the condition of this bike. It is a comfort bike purchased from REI, called the Santa Fe. It is not available anymore. I went to a LBS and they told me I need a size 21 bike. This is a size 22, but I fit okay. (I'm 6'5"). However, the gears and chain are extremely dirty. I am concerned about this failing or jamming.
I know nothing about bicycle mechanics. Would it be worthwhile to take this to a LBS for a "tuneup"? What do I ask for? I don't want to be taken advantage of by them since I am a newbie. What should I expect to pay?
Thanks for any help
