Hi everyone,
I've just purchased an S-works tarmac sl6 frameset with the default ceramic speed OSBB bottom bracket in it.
I'm planning to finish the setup with Sram Red Etap and a Quarq Dzero Power Meter Crankset.
I've made some research to find the best answers about spacers, new bbs, etc. but I ended up asking it here because I hope someone has first-hand experience.
Should I purchase the new Quarq with the BB30 or GXP version? Should I change the default OSBB ceramic speed bottom bracket to make this setup work or are there some spacer packages available which solve the issue for me?
Thank you in advance!

I 'think' you just want the BB30 Quarq, and run it without the large NDS spacer.
Again, not entirely sure on the BB setup, but could be a CeramicSpeed PF30 with 24mm adapters.

OSBB is essentially a PF30 (30mm spindle, 68mm bearing width). quarq BB30 is essentially a 386evo (30mm spindle, 86mm bearing width). So the bb30 quarq + 18mm of spacers is the way to go (they will come with the quarq).

Oh, this sounds cool! So does that mean that I don't have to buy anything just the BB30 Quarq which provides spacers and the original OSBB bb in the frame will work with it?
Yep. Both use a 30mm spindle. Quarq is just bb386 compatible. Think there should be a 11mm drive side, 5mm non drive plus a threaded spacer to do preload. Works out to be a bit over 18mm.

Yep. Or you can buy a C-Bear bottom bracket which is machined with the spacer as part of the body (less moving parts, less squeaking)...

Exactly what I did (other than skipping the Quark meter on the GXP Red spindle). Very pleased.

OSBB on the Tarmac SL6 is a standard BB30, not PF30. Except that I agree with you

What’s even more crazy is the Cannondale Super Six Evo Hi-Mod is PF30a but has a BB30 logo on the frame.

Some time ago OSBB also had a 61mm shell width. Very bad idea.

No matter if the frame is OSBB old style like Calnago writes about, if it's BB30, PF30 och PF386 they use the name OSBB. A bit confusing if you can't see the frame yes.

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?
