The Backcountry Rear Top Tube Pack is a convenient space to store frequently used items and add additional storage to mountain bikes with limited space for packs. The rear top tube bag is design for modern mountain bike geometries and fits the rear of the top tube better than simply reversing a Backcountry Top Tube Pack. It is ideal for stashing snacks, tools and anything that you want close to hand and attached securely to the top tube and seat post with Hypalon-reinforced velcro straps that minimise abrasion.
