Integrated crown race, is that a thing?

[mdvineng]

Wouldn't of thought so, usually they come with their own solution to sealing the dirt out

yours is a separate crown race. but ohlins did make a fork with an integrated crown race for a few years. luckily it didnt catch on

OK, the image doesn't give it justice, but this is the best I can do with the mobile.



I can take a better picture with the macro lens, but that feels somewhat like an overkill

That would take about 30 seconds to remove!

 

[mattr]

most definitely not!

Errrrr, yes, they most definitely do....... quite a few manufacturers are doing it now, along with integrated/hiddensets.

(not in 1993 though!)

Knife from the kitchen drawer. Tap it in where race meets the fork. Repeat all of the way around and lever up. FGS don't tell my missus.

Works for me, but not recommended :facepalm:

Re:

that's very easy, blunt edge hit from under it and work your way around, nice to have thick crown race like that to work with.
But I can see you may have thought it was just the bearing race.

Re:

That just needs a good whacking.

Blunt big screwdriver and 2kg lump hammer. Seriously.

A big hammer is much better than a small tickling hammer. More force, applied carefully.

If that race is not pitted then it will be almost impossible to bend it. It will be case hardened steel, brittle but really really hard.

You are right that the curved bearing surface and the lower black ring seemed joined. That's because they are. They are both part of the crown race, which is sitting on the machined section where the legs join the steerer. In the factory these are whacked on without anti-seize and can be bloody difficult to remove after 30 years. But they always come off.

It actually took much less, once I knew where to hit

It came off very easily in the end. Didn't even need the hammer. Just the palm of my hand on the back of a giant screwdriver.
It threw me off that the bearing surface and the ring were joined. I thought the ring was part of the fork, and thus it was all one piece. Luckily it wasn't the case.
