I don’t own a car, so when I go to the store for large quantities of beer or buckets of cat litter I use the CETMA, a lightweight steel rack that’s tough as nails. I know a couple messengers that have crashed and the rack took the brunt of the force dishing it out to car doors or whatever obstacle happened to be there, and the rack only absorbed a slight crinkle or bend without compromising anything at all in it’s performance. I’ve been using a CETMArack for a couple years and currently have a 5-rail on my ’81 single speed, all-weather utility grocery coffee shop beer bike (a 3-rail is plenty big enough if you only plan an occasional twelve pack or a couple library books; they also offer a 7-rail version!). Keeping the load up front over the front wheel lets you control the weight a bit more and doesn’t bog down like a rear rack. You cannot ride like you normally would, hopping curbs or diving into corners when you have 27 pounds of cat litter on the front. But it’s good to get a change of pace once in a while; a gravity reminder keeps you humble. I also like CETMAracks because of the guy who makes them. Made by hand in Eugene, OR. No outsourcing. No overseas production. And now they even include home-baked cookies with your order.
