Road/Tri Forums and online community?

Hi,

Im fairly new to triathlon and am trying to improve my old road bike with a few newer parts. I've come across from mountain biking and am familiar with that online community and the main websites and forums that they use. I am looking for similar web sites and forums for the road/ tri second hand equpment and chat.



Can anyone recommend me any? Other that this one obviously



Thanks in advance.



James
