Hmmm.. Sounds like a JIS vs ISO problem.. JIS(and sometimes italian) headsets have a crownrace of 27.0mm, while normal ISO threaded ones have a diameter of 26.4mm.. One could coke can shim it, or other options widely available (some kind of cement), but not too advisable.. I'd say, measure the seat of the crown race, get a headset that fits.. Possibly you could get a crown race that would fit the bearings, but you'ld need to test it first..

if it's the original crown race and the original fork, i would suggest the fork seating area has been oversprayed. scrape back to bare metal and it should go on.

I read this as the race was too big for the fork crown. I think it's been "undersprayed" if there is such a thing

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
