I have started occasionally running into folks camping and cooking with 20 pounds or less of gear on their bikes. Also there is a large enough following of the bikepacking movement to support specialty companies like Relevate.
Questioner said planned on carrying 20-30 lb, so no arguing with 20 lb, if she can do her trip with that light a load . I again note, in my experience, beginners underestimate load they will be carrying. Your previous post stated that it is viable traveling long distance fully loaded carrying weight as low as 7 lb. I again say such a target is optimistic for a beginner. Three full waterbottles can weigh 7 lb. When I weigh what I carry for traveling fully loaded long distance, I weigh the bike, ready to go, with waterbottles full, food on board, etc. I again maintain that at the moment ultralight fully loaded bicycle touring is a fringe element, not where I would direct a beginner seeking information trying to decide which type bike to buy.
