The durable and lightweight Adventure Race Top Tube Bag is designed specifically for ultra-distance racing and audax touring. An X21 waterproof exterior, 6oz nylon waterproof lining and YKK Aquaguard zip keep bad weather at bay, while reflective detailing increases visibility and safety when riding at night. Practical and functional, the bag is secured with an adjustable MOLLE Hypalon attachment combined with one of our Fast Straps, allowing the bag to fit seamlessly with all Restrap Frame Bags. The rear strap can be removed to allow the bag to be used as a bolt-on top tube bag if desired. A rigid internal plastic structure keeps the bag upright and stable, and the universal headset mount accommodates all headsets, even on bikes with low stack heights. An expandable mesh side pocket provides storage space for food, packaging and other essentials needed on the road. The inner compartment is equipped with a foam base that provides additional structure and prevents rattling during the ride. Details: - Volume: 1.2L - Weight: 120g.
