Sorry, if it was discussed already: Is it possible to use the new 12s Di2 ultegra on an 11s ultegra cassette on the kickr in erg mode without damaging the chain?

378

yes

Any word on accuracy (or any other issues) with the Quarq on the 9200 rings? Thinking of going with this exact setup on a new bike, but I’m not sure if there are any compatibility issues or not.

It’s perfect, as always with Quarq.

Edit: also dirt cheap :eyes:

You’re making my day! Thanks so much.

Parts availability seems good in the US now for 12 speed ultegra.

Just picked up an R8170 groupset piecemeal sans cranks and rotors.

My brief foray into SRAM 12 speed axs road was fine but shimano quality and shifting remains a cut above.

Hi all!
My DA9200 is coming soon and I’m ready to prep and wax a couple of chains.
I’d like to use a YBN gold or rainbow chains, but I haven’t found any reviews or experiences with their latest gen of 12s chain and the new 12s Shimano group sets.
Has anyone tried such setup?
Thanks

just wondering, the new shifters are not servicable anymore? I would need to replace a broken front plate on a new Ultegra shifter but this does not seem possible anymore.

Thanks for posting this! :smiley: Since I am running same PM and also upgrading to 12sp now.

Question is then, from a cost perspective… since 105 Di2 12sp chainrings are black as well, would be interesting to see how they look on the Quarq…

386

Can’t see if anyone has answered this already, but it’s a TIME frame that is custom painted.

387

Oh, the see-through carbon weave is super sexy. The paint job is nice, too, but I would have totally gone for either the blue or green bike.

DA cranks on the Quarq DFour91, just like @Aeroiseverything :slight_smile:

Looking good, and nice fit!

Looks very good. What „level“ are those Quarq arms? Because they were downgraded from Red to force at some point. Neither is bad, but Red is of course very light.
Mine look very Franken-crank(en), with it saying „Red“ on a Shimano bike.

Nooooo idea honestly. I have one bike with RED crank arms, and one with the QUARQ ones… haha

Total weight is 795g with the 52/36 :slight_smile: 170mm.

Normal kitchen scale so can’t comment on accuracy…

That’s really good anyway. And you have a better PM and crank than standard Shi.

Yeah I love this thing, but I HATE the fucking bolt on these that tend to “jam” (DUB Bolt).

Shimano preload and crank arm attachment is way way better…

But rather have issues taking the crankset off than wrong watts so :wink:
