The Mini Mountain Wedge is packed full of great features, designed to stand up to the rigors of serious on- and off-road cycling. The three-point suspension system consists of a seat post hook-and-loop strap and a 3/4" main webbing strap that threads over each seat rail. A side-squeeze buckle allows for easy removal. A new design feature is the perpendicular strip of webbing on the bottom that keeps a lightly packed wedge from popping out. With added durability in mind, we have lined the wear points of the bag with a layer of SuperTex™ vinyl scrim. All seams are taped to prevent fraying, and stealth zipper heads provide a quiet ride. We even threw in a quick-access key pocket under the wedge for convenience.
