That's in nice shape for its age! Never seen wheels like those, but they're very sharp: tubeless, Baby... Tubeless! I'm waiting for that company, Tubliss(?), to put out a high-pressure, small inner tube, for spoked rims, which will allow me to forego the standard inner tube. Your bike ain't stock, but it has the makings of a fine ride. I agree: I'd replace the seat and the handlebars, as well. Otherwise, it is really nice. Cheers!
