So I am finally making the dive into bikepacking with the purchase of a Salsa Fargo 3. It is on its way to my apartment now, and I am already thinking about the rackless setup I would like to make. I'm thinking that a handlebar bag, frame bag and a couple of feed bags like those Revelate Designs makes would carry my UL setup I use for backpacking. I may eventually try my hand at a seat pack so that I can ditch a pack altogether, but that will take some planning, I think.
I'm really just working on the fabrics I'll use for these pieces. My priority with fabric choice would be price, durability and then weight. One thing I have noticed about these products is that they are made with some seriously tough fabric. A lot of the reinforcements seem to be made using ballistics nylon or fabric such as 1000D nylon. I know fabric like VX21 is tough, but also costs quite a bit more than similar denier oxford nylon.
So here is my question, are these products being over built to work in any situation customers can come up with, or is the constant rubbing against the frame enough of a factor to make reinforcements of this caliber necessary? These products are all very popular, so I figure they must be doing something right, but I just wanted to hear anyone else's experiences with fabrics for these uses.
