Sorry to jump on this thread.....
I'm thinking of getting a S-works SL6 Tarmac, either disc or non-disc.
Part of the appeal is the ceramicspeed bb which takes 30mm axles cranks but from what I can see, I only a few options for the crankset right?

1) S-Works Carbon crank.......which they discontinued
2) S-Works Carbon Power Crank....the above with their in-house power meter
3) Quarq pm bb30
4) NON AXS SRAM Red or Force bb30 cranksets

If I want to use others such as Shimano, Campy, etc, I need to either use adaptors OR I knock out the factory ceramicspeed bearings and replace with 3rd party?

Is that correct?

Other 30mm spindle cranks too. Easton ec90, rotor aldhu or 3d+, Cannondale hollowgram to name a few

If you want to use a shimano or sram gxp you can still use the ceramic speed bearings but you will need an adaptor. Better setup would be one of the collet bbs like praxis makes.

For the money I sold my new BB30 CeramicSpeed bearings for on ebay (that came with my new SL6 frameset), I only had to pay a small upgrade fee to buy the full CeramicSpeed BB30 bottom bracket so I could run Shimano Cranks.

After hearing the horror stories about creaking BB with the Adapters, I wasn't going to entertain going down that route. The proper BB has been faultless by the way (as you'd expect), no creaking whatsoever.

I bought the S-Works cranks for mine so I could run the CS stock bearing, got them really cheap on eBay, they are super stiff and light, then I bought the Quarq spider for them. job jobbed. They've been totally silent also.

Another related question. I ordered a WheelsMFG bottom bracket for my Quarq GXP..

The Wheels MFG Manual says that one should use grease when installing in carbon and anti-seize paste when installing in titanium.

Has the S-Works Disc titanium inlays? What should I use?

It has aluminum alloy inserts. Anti-seize is just grease with a sacrificial anode in it. You could use anti-seize if you want, but since the conversion BB is also aluminum alloy, you wouldn't have to worry much about galvanic corrosion with just a nice NLGI-2 "marine grease."

My SL6 has now + 8000 km's done, in fair conditions, when it rains i'm on my mountainbike. After this mornings ride when i heard some creaking noise, i checked my crank's for play on the BB.
It seems my Ceramic speed is already wasted??
Is this normal for Ceramic Speed?
Get steel bearings, never look back.
Ceramic bearings are bunch of marketing bs. They might roll better for a race or two but will degrade into a worse condition than steel bearings in no time.

Correct. Highly recommend you get a proper BB instead of using adapters though.
