I got one of those surly cornerbars (offbrand) and they're fucking great, would recommend to everyone. Easily the most comfy handlebars I've ever owned.
Also currently trying to piece together the perfect small size at most medium weight bicycle EDC pouch to chuck in my panniers so I can field repair my entire shit and also help other people.
Pretty sure I'll put some bar ends in there just to slap them into random bicycles so people don't core sample themselves. I am the velocipedal crusader, you will be saved from doctors having to extract a tubular 21mm cross section of yourself so they can figure out what the fuck you managed to lose because you didn't think to put 50 eurodollarcents of bar ends on your stuff.
The corner bars look like a great option. I have a set of drop bars on my gravel/everything bike and the brake levers I went with kinda suck (I have downtube friction shifters for sturdiness, reliability, and serviceability) so it'd be nice to use mtb levers with some more versatile bars.
Speaking of, I'm a little scared of riding since I haven't seriously ridden since gaining a lot of weight. I'm also tall so I'm well over the max rider weight for most bikes. I've already chewed up a square taper crank arm. But my parents might help me get a sturdy frame, like a Clydesdale.
