supossedly the Shadow chain is the strongest, also look at the Kink Fatboy and that big KMC chain....as for forks....S&M Pitchfork's and Odyssey Dirt forks....both have warrantys....S&M even had some sort of 1,000 year warranty on their pitchforks like a year or so ago...i think it was a joke though...as for the spokes.....
wait a while and then look on
www.bmx-test.com (found out about this site about 2 months ago and its great) sometime soon theyll get a test in there....
