The Velo Orange Rando Bars* come in a wider option (48cm I think), but they are still only about 40-41cm at the hoods, and have more flare (out and up) than the Nitto.
If all you want is a little bit of flare outwards (not the up or back bit) then the Velo Orange** Grand Cru are well worth a look, I have a pair on both my Audax bikes now, the flare is not as extreme, ie: not ‘Grrrraaaaavvvel!’ levels of flare but it is enough and a great bar for comfy road riding a occasional unsurfaced tracks.
Both the VO bars are quite long reach on the ramps though***, so you may need a shorter stem if you’re used to compact drop bars, and they are traditional bend, so make sure you’re happy with that and your levers suit. bars are so personal it can take a bit of experimenting to work out what you like.
* There’s also a pair of those in my loft, but they’re waiting to go back ona bike 😉
** VO only come in 26.0 but pletny of stems available still.
