B'TWIN Fit 5 Road Bike handlebar diameters

[PedalCat]

Hello. Does anybody know the diameters of the Decathlon B'twinFit 5 handlebar? It appears fatter in the centre, and slimmer where the levers/shifters clamp on. I like the idea of bullbars. Before anybody mentions drops, i do not get on with them and never will.
I'm happy to ask Decathlon, but i wouldn't be surprised if CycleChat is quicker.
Thanks in advance.

31.8mm I expect.
