Those are generic aluminum handlebars. I think they have something like 90mm of rise and 8-9 degrees of pull-back and maybe 60mm wide. I've replaced them with a Profile Design bar that is 60mm rise, 9 degree sweep and 66cm wide. I picked up an 83-84 MTB on Craigslist and I really found the 69cm wide bar to be comfortable (not useable on my bike due to odd clamp area size) so today I ordered a bar with about 40mm of rise, 9 degrees sweep and 74cm wide!! I'll see how I like them.
