Going to change up my riding position on my rocky mountain a tad. Interested in bar like this. What are my options (apart from the Ritchey which i can’t find in aluminium in the UK)

wiggle are doing those Ritchey ones in aluminium.

on one mary?

Salsa do a pro moto flat bar with 17deg of backsweep. Not quite the same profile as your pics but might put your hands in a similar position

Also surly torsion bar? Ragley? On one?

actually, I have a brand new pair of these;
