Got given some nice Dura Ace R9100 cranks but no chainrings, apparently 110bcd but 4 bolt holes look off-set to me - will (cheaper) 105 / Ultegra 11 speed 110bcd chainrings fit okay (which also look offset)? Cheers

Providing the 105 and Ultegra are the newer 4 bolt design they'll fit.
Absolute Black make competitivly priced chainrings that fit DA9000 onwards, they're oval but could be worth a look.

Isn’t the ring offset different on DA than others or am I mis remembering? The gap between the rings I mean.

Yes Ultegra r8000 chainrings will fit. https://bicycles.stackexchange.com/questions/59218/r9100-chainring-and-r8000-crankset

Can I interest you in a little used set of Absolute Black 50/34 oval chainrings that will fit 🙂

It’s a 50/34 pair of these. £145 new. Very little use (few hundred miles). £95 posted. Obviously only going to be of interest if you actually want to try oval chainrings. https://absoluteblack.cc/oval-road-da-9100-ultegra-8000-chainring

I've got those Absolute Black on my FC-9000 Dura Ace. Very good they are. I'd be tempted, but mine aren't very old.

Got some off ebay for £30 the pair, inner DA one fine, but had to file the outer Ultegra ring near one bolt hole down a bit as the Dura ace cranks are fatter/wider just in one place. Test rode it this afternoon, all's fine now, thanks for help.
