The Dual is a super-compact and efficient way to carry the basics for fixing a flat. Two tubes, an inflator, tire levers and maybe a patch kit too. Because it does not wrap around the seatpost, it fits on tri bikes and road bikes with aero seatposts.

Specifications

• 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 MTB tube and gas, no problem
• 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
• Size: 27 cu. in.
