I've got a bike with no provisions for mounting a standard rear rack.
I'm wondering if the seat post mounted racks are worth anything? The quick release models by delta are tempting, but I havent held one in my hand to know if they are junk or not.
I've heard a little bit about them swaying like pendulums and twisting around, but that was from somebody that wanted me to buy a touring bike.
Thoughts, opinions, expierences?
