Topeak Super Tourist Rear Rack w Spring
The Super Tourist rack is perfect for someone who wants a cheap, strong, dependable rack. It's pretty easy to fit, and will hold lots of gear. The integrated spring clip is convenient for securing lighter weight cargo.
This rack will fit onto almost any bike that has frame eyelets for the lower struts of the rack (which is most bikes). Even if your bike doesn't have eyelets on the seatstays, you can use P-clips to attach the upper struts of the rack.
