wow, thanks for great responses! wonderful to hear about other people who have ridden peugeots, mixtes and other older bikes on tour!
in response to dave, i am a 1.5! i plan EXTENSIVELY for certain aspects (i'm prettymuch a born and raised hiker, didn't go on my first fully loaded bike tour till 4 years ago, so still tend towards worrying about food, water and first aid supplies) and forget fundamental bike points until the last minute when i then freak out!
i had a full tune up about 2 months ago, not sure if the cones and bearings were lubed at this time, the freewheel and chain were replaced, so maybe the back one was...but that is something i'll make sure to do before leaving.
i attached a water bottle cage to the handlebars because i didn't want to mess up the peugeot decal on the down tube, but i'll carry extra bottles in my panniers and switch out as needed.
i do plan on carrying most of my weight in the front panniers and tools in a handlebar bag, so that'll keep the heavy stuff off the rear axle.
