Durable and lightweight, the Adventure Race Top Tube Bag is designed with ultra-distance racing and audaxing in mind. An X21 technical waterproof outer, waterproof 6oz nylon inner lining and YKK aquaguard two-way zip keeps inclement weather at bay, whilst reflective detailing boosts visibility and safety when riding through the night. Built to be practical and functional, the bag is held firmly in place with a rubberised velcro strap and an adjustable MOLLE hypalon fitting, which allows the bag to function seamlessly with all Restrap Frame Bags. A rigid internal plastic structure keeps the bag upright and stable and the universal headset fitting accommodates all headsets, including bikes with a low stack height. A stretch mesh side pocket provides storage for nutrition, wrappers and other on-the-fly essentials.
