Absolutely fine on my Road bike (Ultegra 11sp / dfour91) - but this is with shimano ultegra chainrings . Also have same setup on the TT bike and that's been fine (ultegra 10sp, and 11sp ultegra / DA chainrings on Quarq). I even use that same quarq on my 9sp ultegra trainer road bike and that's ok, but the front ring shifting is a bit rough, but then that's expected as it's a mix of 9sp chain, ancient front mech, 11sp rings and flexy as a paper alu frame.

Then one thing I didn't like was SRAM chainring on a previous s975 quarq. But that was as the ring pringled after 2 months and then I bent a tooth, so that was what prompted the original change to shimano rings.

On my MTB I sorted a lot of the shifting problems with the SRAM drivetrain by swapping to shimano chain and cassette.

I Just installed a Quarq Dfour91 on my P2 which has everything 105 (except for the FSA crankset). I upgraded to Dura-Ace Chainrings because I think it looks better. But it should be plug and play with 105, Ultegra, and DA.

Everything shifts and works nicely so far.

I have 4 sram/specialized w/sram chainring quarqs mixed with 9000m/9100m/8000di2/91000di2 and have had no issues with any of them.

Cool, thanks. I neglected to note in my original post that I'm specifically interested in a dzero with SRAM chainrings compatibility with a shimano drive train!

I've got SRAM TT chainrings on a Quarq with complete Shimano drivetrain on my TT bike...never any issues. Have Praxis chainrings on a Quarq with complete Shimano drivetrain on my road bike...never had any issues. Have WickWerks chainrings on a Quarq with complete Shimano drivetrain on my CX bike...never any issues.

I have Elsa's, Specialized and DFour91's and they all work great. You will have no issues.

Thanks all! Sounds like the extra $$ for a DFour and shimano chainrings is not needed and that is great because I don't really like the aesthetics of the shimano cranksets anyway!
