I have a Nitto, mustache bar and dirt drop 8 stem.
close and a bit higher than the saddle.
bar end shifters and some older, pre Aero, Campag road brake levers..

+1 the hand position is typically on the forward curve,
within easy reach of the brake lever.

If a mountain bike conversion, Trekking bars, are an easy swap ,

It is possible to set those up with road brake levers on the forward bend,
somewhat like mustache bars.
tubing is 22.2 , though.. road is 23.8 [7/8", vs 15/16"]
