Arundel Arundel Seatbag

DUAL
The Dual is so named because you can fit two 700c tubes, two gas cartridges and a gas valve, plus have room left over. Alternately, it will fit an ATB 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. 27 cubic in.

UNO
Unos are small, only big enough to carry the basics for a flat change. The Uno has a very small footprint under the saddle and weighs almost nothing. 16 cubic in.
