Do you Bike? Need your input please!

I bought a second hand quality bike off of pinkbike.com. they have a ton of information about repairs and maintenance. I fell in love with mountain biking. I'm still a novice, but it is an amazing full body workout. I had a knowledgeable friend pick out 3 bikes for me and I managed to get a bike that would have cost me $4000 new for $600. It depends on what you are doing. I needed upgrades for the rock terraine. I scoffed at the idea of spending so much on a bike, I had a cheap one and when I upgraded my whole outlook changed.

I like Norco. If you want to see hilarious names for bike models, look up Cove bikes.

What amazes me is in the years from when I bought this bike. It went from casual biking around the neighborhood to so much more!

Thank you for your suggestions!
