Anyone tried a setup as title describes? The idea is to convert my flat bars into something kinda like a Jones H Cut bar or a Velo Orange Crazy bar. As you might imagine, this is for bikepacking, will probably use this hand position while on long gravel/dirt roads.

Not my bike, but I'm talking about a setup like this:


If you've done it, did it work well, and are there particular bar ends you'd recommend? Seems it'd be best to find something that flares both inward and up towards you, so you can leave your hands there without fully gripping them. And possibly slip a foam grip over 'em?

I have done that a couple of times, though I prefer to use them on a bar with a bit of bend in them. They work fine to give another hand position.

I know of a couple of MTBers who swear by them mounted inboard.

isn't it awkward not having any arm supports?
Ive never used aero bars, but for ages I have used mtb bar ends to get lower down, and as I do use trekking bars, I could see how with these one could lean slightly on the closest part of the trekking bar to give some support while reaching out to the frontward pointing out bar ends.
I even sometimes lean on my trekking bars like this and do a "time trial" position, although that particular bike is a bit twitchy, so I have to be careful. I do this position on dropbar bikes and it works pretty well, so I can see how it could work well on trekking bars.
I guess my question is, Is it worth having these bars sticking out and in the way if you hardly ever use them?
I guess there is no clear answer to that, and I'd have to live with them for a while to see.

Seems relevant:

I have aero bars on one (drop-bar) bike...I don't find it esp comfy or confident to hold on to the part near the main handlebar which is roughly equivalent to setup described above. & that's on fairly smooth roads. YMMV though.

and as an added note, an old acquaintance of mine, who is a doctor, and serious biker, always considers bar ends to be dangerous pokey things in your chest or whatever in the event of an off.
He mountain bikes and whatnot, so knows the biking side, but maybe his view is shaped from seeing ER visits of folks who have had impalings etc in car accidents and colours his view of the danger with bar ends.

I've ridden with bar ends on mtb bars for ages, and really like their position, like mentioned in that article.
So crazy as it seems, I might try this goofy setup one day, just for giggles.

Why not sew a handlebar bag to slip over rhose bar ends ? Final Configuration unknown

so you get it sewn rather than just bought..

Some more discussion here: Bar ends: did you feel crowded?

There are a couple good pictures of people doing what you're talking about. Hope that helps.

SQ Labs makes inner bar ends that look wonderfully ergonomic.

Those SQ Labs bar "ends" look nifty, instead of being curved toward the end they're shorter but with a flare to help prevent slip.

Had them on an older bike. Loved them on the inside

1997 called, they want their Spinachi Bars back.

Hey Olive Oil, where's my can of Spinachi?
