I was about to install a new headset and put my fork back on my frame when I noticed the fork crown race had a small crack in it that is almost through the entire lip/ring. I'd like to replace it and avoid a failure at an inopportune time.
Even if the race was not cracked, it still doesn't fit into the new headset I purchased. (does not go inside the bearing cartridge)
Here is what I'm working with: mid-80s road fork, 1" threaded, Shimano 600 NOS headset.
I can provide pictures or more information if needed. I guess I'm trying to figure out where to find a variety of fork crown races. I called my LBS, told them my issue and was informed that they didn't have any races that would work since it is hard to match headsets to races and even more difficult in my case since the headset is old.
Any ideas? Did Shimano decide to change the diameter of the headset bearings cartridge and complicate things?
