For me, you have the wrong bearings. Take a look here http://www.fsaeasyheadset.com/configuration/ C-40 and N°42 are different ones. I could be wrong, but looking at your pic, the angle of the inner face of your bearing doesn't match the angle of the crown race. Did they ship the frameset without the headset?

I think you're right that I have the wrong bearing but... there are six headsets on that page listed as no42?!

Yep, that's what I told to myself : "good lord, all those different n°42 headsets" Good luck with that :?

Correction, now that I see the images on a full size computer screen, the bevel of the bearing makes it pretty apparent to me that it is the wrong lower bearing!

The wheels I built from a Bdop cycling kit: Novatec centrelock hubs, Cx-ray spokes, carbon 40mm deep 26mm wide rim. They are lovely rims, 410g, tubeless compatible. They’re wearing Schwalbe One tubeless (original not Pro) in 28mm width. They weigh a ton, 390g, but they roll really nicely.


Is 410 grams a actual weight? That would make me even more disappointed with my Hongfu-sourced UAM AR40-T (tubular) rims which came in at 405 grams each (380 claimed).

The Hongfu FM079-F frame I used is at least considerably lighter than your B36 at 1060 grams for a size 50cm, and 400 grams for the uncut fork.

My flat mount TRP HY/RD calipers are also marked 'HY-ROAD'.

Yes, I weighed the Bdop carbon/disc/tubeless rims at 410g each. The bare wheels built up to 690g front, 810g rear. Kind of a shame about the disc rotors and heavy rubber, lol.

I got a new lower headset bearing today, ACB 36/45 52mm OD. It's the correct fit and the fork/frame interface now looks correct.

Glad you got your headset sorted :thumbup:

I like it. Kind of tempted to get one myself. Too many bikes though and there is not space in the garage for another.

-> Can I ask what exactly you ordered/where?
I am building a Fm-008 atm (viewtopic.php?p=1343958#p1343958) and just installed the Hengfu headset. It is heavy and I have the feeling its not too tight simply because of the bottom part where the bearing is sitting on the "oval shaped" ring at the very bottom. Do/did you have some clearance there, too? Did you solve the "gap"?

That bearing description should identify it enough? I went to a local shop that has a decent workshop and they were able to supply the correct bearing. Its inner edges are more chamfered than the bearing pictured on p1 of this thread so it sits lower on the crown race. Fork now sits closer to frame, as below.

Your new build looks lovely and will be very personal. That's the payoff for building your own bike.

The ever-helpful Nancy at Gotobike provided this photo of what I presume is an FSA technical catalogue showing details of the required headset. Lower bearing id is FSA TH-073E ACB 1.5.
