I thought it might be interesting to start a collection of users bike related bookmarked web sites. If it’s popular enough it could be a useful reference tool and sticky’d.
Anyway, Include the sites name, link, and maybe a description (feel free to expound upon submitted entries). I’m sure a lot of these could spare mentioning but who knows. Feel free to include a rating of 1 to 5 
.
My bookmarks, for the most part, can be broken down into the following categories:
Discussion forums, instructional, builders, blogs, and a few random references.
Forum:
