Trying to make a new race,go on my FOX 36 (2020), its not split and needs to go another 5or 6mm.
I put it in boiling water, and greased the frozen fork,tried tapping it down with an adjustable wrench but the race is ally too, so I couldnt wack it
The only thing I can try tomorrow is start again with a big tube of the correct ID
Will it FIT,or have I missed something obvious, like the crown is not made for Fox?
Can I cut it and use it as a split race?
Assuming they are sealed bearings just pop a small cut in the race with a hacksaw.
Cut it and smooth the edges - fit the cut section of the crown race at 90° or 270° onto fork (you don’t want the cut section top/bottom)
Thanks to Soma and cyclistM! Thats a weight off my mind, I'll be able to get some sleep tonight. Maybie
Was I being too optimistic hoping it'd fit?
I don't think it's that tight, deffo be William next, Charlie won't live long enough for George to be a shoe in
Ahhh, a new 'Crown race' thread. It's been too long!
I just tap them down with something 'soft' - usually the handle of a rubber mallet, tapped with a hammer. There's a 'lip' before a flattened section. Once over the lip, it's all downhill.....
As above, just done one that seemed too tight. Got an old bearing sat it on the new crown race at tapped it down with a hammer working my way round so as not to push one side down too much.
Was I being too optimistic hoping it'd fit?Modern big steerer forks there's too much difference between this size and the next size for any confusion. You've either got the right size/parts or its painfully obvious that you haven't. In the olden days we had two or three different sizes of 1" headset that were *almost* compatible. But not.
You probably need to hit it harder or hit it with the right tool.

Tube, hammer, support underneath the fork crown with one hand (don't rest the dropouts on a bench and then welt it 😉 )

Its only a 45 degree taper, for the bearing to sit on, so splitting it and expanding that ring a few thou" shouldnt matter? its still 45 degrees on the taper, and the preload on the bearing will hold it all in place.
