Just a quick shout-out to Shimano. I wanted to make sure I had the headset pieces put back in the correct order and didn't have the bearing cartridges flipped up-side-down so I went to their site expecting to find nothing. Their Manuals and Tech Doc site is awesome! Manuals & Tech doc They had an exploded drawing of a circa 1999 HP-6500 headset. I never expected that.
