Out of the loop - MTB components
I'm thinking about getting a mountain bike, but I don't know where to start looking! I know a lot about road components, and I know it's a good idea to get at least Shimano 105 components for a road bike. Is there a similar equivalent for mountain bikes? What happened to XT and XTR? I haven't had a mountain bike in 12 years and it seems like a lot has changed. What should I expect to spend for a decent mountain bike? If this is a question that gets answered a lot, just point me to some old threads :o
