If you are tired of the banners and pop-ups and general "what new bike to buy" threads at MTBR, check out Nationalmountainbike.com forums. It's by the guys who started Nashvillemountainbike.com

The crowd is still small and mostly TN based. Much info there on TN trails and almost daily conditions reports.

And Sorbachattanooga.org has the BEST trail guide for the Southeast.

I've been off the bike for a couple of years, but am getting back into it heavy this year. I'll do some group rides (road), but am mostly a trail rider/racer. Planning several races this year with surviving the DirtSweatandGears 12-hour (May 3) being the top priority. I'll be racing that with a CA transplant in the Duo category--which allows gears, but we'll be SSing it.
