I got an Oddity Razorbar. Handlebars are expensive these days, wasn't that much more for custom. Could be great for loaded touring in extreme terrain. Me, I just think it looks cool. Illustration 3.
I ran Jones Bars for a long time on my singlespeed, I generally like the "wheelbarrow" hand position better than the "chickenwing mountain bike handlebar" position (no offense) -- among other things I felt my "suspension" worked better with em and found it easy to weight or unweight the front end as required.
Have recently had a thing for MX-style handlebars (with Oddity's "Oddmone" being the prettiest I think) before I realized I could buy, you know, actual MX bars for cheap on craigslist. I dig em (even got em a front brake eventually). Illustration 1.
I don't know if you consider North Road bars as "alt bars" but Nitto Bosco is as close as it comes to a plug and play solution for 90's mtb frames. Two decent hand positions, as with Jones with the same advantages. Someplace to grab hold of if for some reason you want to get all aero, or room to mount a bag, which is more civilised. Rise and reach are perfect for those frames (and their ridiculously long stems) Illustration 2..
My wrists just aren't built for 9 degrees of sweep, 18 feels about right to me (hence the custom bars) and the MX bars are close enough. As for street bars, I think I like straight back more than the Jones 45 degree sweep. Feels more like street handlebars "should," ya know? Coming up with drops and all.
that's a decent idea with the bar ends
