Can someone tell me where on the Net I could buy some
new comfort handlebars for my Marin bike ?

Even with the stem/handlebars in the highest position , I lean a
little
forward and I want to sit more upright. I'd like to find some
handlebars
that have more upright angle to them.

I realize the bike frame
may be too small, but I don't have the money to replace
the bike at this time.

Thanks,
Carl
