The Topeak Aero Wedge Saddlebag is perfect for on the move adventures as it has plenty of room and expands to give even more space. The bag is aerodynamically styled to save weight and prevent chafing and will hold tubes and tools comfortably. Velcro strap mounting holds it firmly in place but also makes it easy to remove if you want to swap between bikes. There's also a reflective strip for added visibility and a handy rear light clip.Key FeaturesMade with 1200 Denier Nylon, Dupont Teflon CoatingCapacity of 90-120ciNylon Straps/Buckle fixtures3M Reflective StripRedLite ClipExpanding designLarge: 11.4x21.6x14cm, 1.48-1.97L, 176g
