i would like some recommendations on rear and front racks, as well as panniers. i'm planning a cross-country ride this summer so something sturdy is key. should i go with steel or aluminum? what about size? i am leaning towards getting steel racks (nitto or IRD) since they are stronger and i just like steel. i know very little about panniers (just ortlieb and baggins). i will be riding solo and i plan on mostly camping so i guess i need something with more capacity. also, where could i purchase such products?
