Wanting to convert my wifes road bike to a flat bar. Have been thinking about sram attack twist shift. Will this be compatable with Ultegra F/R deraileurs?
Thanks

yes

Which SRAM shifters are Shimano compatible the numbered or the name version? I heard that SRAM is doing away with 9 sp and under twisties. https://forums.mtbr.com/showthread.php?t=610981

I recommend that you consider trigger shifters rather than twist grip. Much nicer and more positive. And it's easier to change the grips, which wear out at a surprising rate.

...and much easier to replace cables (replacing twist grip cables can be a nightmare)

and trigger indexing stays fairly accurate for a long time whereas grip shifters get sloppy after lots of use, causing crappy indexing.

Yeah. Grip shifting looks sensible, but no one who uses trigger shifters complains. They really are the best.

Maybe the OP has a mountain bike with grip shifters and wants to stick to that style of shifter? Maybe the OP wants to ride in the snow wearing ski-doo mitts in which case grip shifting is much easier? I don't think the merits of shifting systems is what this thread is about; we don't have enough context to recommend one system or another.

Implies the decision has not been made final?

So we gave some facts and opinions to help in the decision making process.

Was that offensive?

Nobody said "offensive".

SRAM Attack is the name of the line that works with Shimano rear derailleurs, the X.n series you need a SRAM rear derailleur.

Although if you go with trigger shifters, the front derailleur will need to be replaced. Shimano and similar flat-bar front shifters don't play well with an Ultegra front derailleur. You need a FD-R453 or similar to make it work "right".

name versions are compatible with shimano RD's.. front shifters have sort of a power ratchet so they can operate most FD's by ignoring the numbers

why spend the money on levers shifters and bars to to have less hand positons?

A big advantage of the twist/grip shifters is the ability to use any front derailleur with them. I have a commuter bike that has a Shimano 105 front derailleur (and crank) that is shifted with a SRAM X7 grip-shift, and works great because of the multiple positions that the grip shift gives you. I just got some SRAM X0 grip-shifts for a mountain bike, and was surprised to find that the front shifter only has the three indexed positions, and no intermediate positions; it's not a problem for this application, but it means that you'll have to check whether the grip-shift you buy has just three positions or many (the one that I have which has many is a SRAM X7 from 2007).

As long as the number of cogs on your cassette matches the number of speeds on the right-hand shifter, that should also work fine if you get something from the SRAM Attack line and a Shimano RD. Until SRAM XX, the SRAM road and mountain bike cable pull ratios were slightly different, and so don't try to use the SRAM X.? shifters with a SRAM road rear derailleur (only do so with a SRAM MTB rear derailleur).

Flat bars are more comfortable for many people. If you're not riding far, you don't need many positions. I have bikes with drop bars and bikes with upright bars. I prefer to be upright for slow or short rides. And some people never get comfortable on drop bars.
