Topeak Aero Wedge DX Packs Medium, 7.5 x 3.7 x 3.9

The aerodynamic wedge shape lets these under seat bags slip easily through the wind while the internal pockets keep tools away from inner tubes and other delicate items. The DX Small is the perfect size for a road tube, and essential tools for roadies. The DX Medium provides just the right amount of room for an MTB tube, patch kit, and a tool for mountain bike use. 3M Reflective Strip RedLite Clip Material 1000 Denier Nylon Dupont Teflon Coating Bag Attachment QuickClicktm w
