The Topeak D-Flash Express S is the fender you keep in your bag for the ride home that turns wet. It straps to your saddle rails in seconds with hook-and-loop straps, no tools and no assembly, and it keeps the stripe of road spray off your back.

It ships flat. Fold it along the perforated line, wrap the straps around your saddle rails, and go. At 16 grams it disappears in a jersey pocket or the bottom of a pannier, so it is there on the days the forecast is wrong.
