yeah, go to sheldon's page for info on converting.

also, please take this advice on behalf of pretty much everyone:

for you own sanity and well being, don't fuk with old peugots. older french bikes tend to have odd sizes for everying and a bunch of bolts and crappy geometry and they weigh more than a car and... there are a lot of disadvantages to old peugots.

so you may want to consider that.
