Probably a stupid headset question - carbon (road) forks with no crown race?

Sorry, couldn't resist paying homage to the other thread...

I received a new road frameset which was beautifully packaged and appeared to come with everything required for the build, except the supplied headset came with no crown race, and there is nothing on the fork, although there is a shoulder on the fork before the crown which appears to fit the bearing perfectly.

Everything slots together and spins fine with no preload (haven't chopped steerer yet) so is this common enough? Am sure I read the crown races were almost just to protect the fork from wear so guess it might be reasonable that a road fork doesn't require it?

Have contacted distributor but not heard back yet

Yep, quite normal. The bit that contacts the fork crown shouldn't move; the bearings and the outer race move in relation to it. No different to the outer race contacting the head tube.

Needless to say check regularly that the bearing doesn't seize due to muck from the front wheel

I've got 3 or 4 road forks like this, going back ~15 years.

It's not new, or particularly unusual.

Awesome, thanks guys.

I've never actually built a road bike up from a frameset before, my only experience with carbon forks is on the CX/gravel bike and they still used crown races.

😎

Will transplant the slightly baggy old Ultegra drivetrain across from my Rose as I suspect it still has a year or two of dry summer miles left in it, but will stockpile new bits for when it eventually wears out. Have new Ultegra brake callipers to allow 28mm GP5000s which are hanging in my 'office' degassing and making the room smell like a bike shop 😂

Existing Fulcrum 3 wheels because it would take serious money to really improve upon them, although next year I'll probably treat it to some shallow section carbon wheels, lop 100-200g off and make it a smidge more aero.

My only reservations thus far is that Basso's stated frame weight was WILDLY inaccurate and I'm worried that the final build will be no lighter than the triple butted aluminium Rose it replaces, but it won't be any heavier and almost certainly stiffer which I'm looking forward to trying whilst stomping up the local climbs. Just shy of 1700g frame and fork.

Yep, I didn't trust it at first just putting the bearing directly on a 45deg composite cone with no other race or anything, but it's the done thing it seems and I've not died from it yet....
