Worked:
UNO Stem
Zero Gravity Brakes
SMUD Seatpost Yoke
Corima Wheels & their red brake pads.
Corima wheels as WW option???
Corimas rims are pretty heavy compared to ex: Ax Lightness, Schmolke etc
But they are not rubishly flexible :) 290g for the 32mm (and 320-330 for the wide version) is good and available in any spoke counts.

It's a huge difference between clincher and tubular rims.
Part from that, you mention a rim weight of a rim that is only 22.6mm wide. No-one will use that anymore.
Further more, the rims weight more than the spec says (ask someone to put a rim on a scale and you'll see)

22.6mm wide?

Website says 26mm...rim width is down on my list as a consideration anyway.

What WW parts doesn't work?
Do you mean actually failing components, or components that just annoys you?

Anyway, it seems to me, this is subjective?
I have components i would stay away from, but that doesn't apply to everyone.

Almost all worked, so it's better to say which few didn't.

1. Sub 40g skewers (Tune, Carbon Ti) - sooner or later creaking on back wheel.
2. Climax setback seatpost - major discomfort, like sitting on a glass pole. But, relatively cheap Far East production, so no surprise here.
4. Titanium clamps for Dura Ace 9000 shifters (from Titanium Planet shop) - constant slippage. I was return them and not even got refund. Titanium bolt for Superlogic seatpost is fine (for now, at least), but all in all, web-shop to avoid in future.

I also get Ti clamps for DA 9000 shifters and Ti spindles for DA R9100 pedals. The clamps are used for DA 9100 shifters as both of 9000 and 9100 has the same clamp part in the EV documents on si.shimano.com.

They slipped at first mount. I then compared them with the origin steel part, resulting in Ti nuts 1.5mm longer. Thus I machined them shorter but still didn't work. I found the threads on the last 1/5 of the nuts is not well machined, so re-threaded them. Finally they works. Now I just think the Ti clamp nuts they sell are just 10mm nuts for calipers as I see something similar on aliexpress.

Ti spindles for pedals works as what it should be. However, there is no L/R mark on them which should be there on the pictures. The surface doesn't look like fine machining anyway.

In conclusion, although Titanium Planet is from switzerland, I can not see any "Swiss Quality" in their products. The quality of their products (at least what I got) is much lower than that of S-parts, which is the best Ti products factory and seller in China.

Don’t they come by default with Ti clamps? 9150 for sure, but quite sure I had them on my 9070 too...

25 mm tubular tire isn't that bad on 22,6 mm rim... Best part is you can find these narrow wheels really cheap. :D

Mine 22,6 wide 32 mm S+ tubular wheelset weight 1143 g, just 13 g more than spec. Don't know how much those hubs weight but atleast wheelset is pretty close. Not real WW but feels pretty bombproof and stiff.

The bolts and nuts are not Ti. The weight goes from 13.X gr to 7.9 gr

First ride the saddle snapped in half going over a small bump. This caused the contact point between the rails and saddle towards the front to detach itself. It was a shame as it fitted me well. I've since bought 2 Lupinas and and a Dila and have had no problems. These models feel more structurally sound particularly the Dila.

Ive broken Lupina(2).. but not the Dila, but I have also not ridden the Dila but a couple rides as I does not fit my style.
