I got this bike (a Peugeot Nice) in a police impound shed (free), and have been riding it about 6 months. I like it better than my Schwinn Crisscross

However, the CTA stem and stock Peugeot bars are too low for me, and uncomfortable on a 10 mile one-way commute. I'd like to replace them both with something more upright, but have no idea where to start. Can I even do something like this? Where do you get more traditional upright type bars? I'm lost with the "threaded headsets" vs. "threadless" etc. stuff, or if it is even appropriate here. And then there is the "French" factor - I'll have to check the sizes for getting the right replacements, as standard stuff wont' work, right? Where do you buy replacement items like this? Performance etc.?

Sorry for the newbie ignorance!?

Cheers!
