Wondering what you Urban Express riders out there are using for storage. So far the best option seems to be these guys from Sunday Morning Motors https://www.sundaymorningmotors.com/product-p/c010023.htm
Which looks the same as what's on this Express http://photobucket.com/gallery/user/macadamiaman/media/cGF0aDovRFNDXzg2NzFiLmpwZw==/?ref=
I like that each one clips onto the top of the rack, not straps going under the gas tank. Any other recommendations though?
