Hello all--

I'm somewhat new to the mountain biking world. I rode BMX hardcore as a kid and I've decided to pick back up biking. I own a 09 Trek 6000. The components are decent for my experience, but I am looking to upgrade. I am looking for websites and/or information that "grades" or "ranks" various components...a good, better, best type of thing. Any direction or information will be great.

Thanks to all.

NS
