Arundel Dual Seat Bag

The Dual is so named because you can fit two 700c tubes, two gas cartridges and a gas valve or an electric pump, plus have room left over. Alternatively, it will fit an MTB tube and gas, no problem. The leather patch prevents the seat post clamp from wearing a hole in the tubes inside. The simple Velcro strap is sewn double-thick to hold its shape and to keep the bag cinched tight. 35 cu in.
