The smallest Fumpa pump the rechargeable nanoFumpa measures just 1"x1.8"x2" and easily fits into your seat or frame bag.  Weighing a scant 100 grams it inflates one tire up to 80 psi on a single charge and fits both presta and schrader valves.  If you are tired of CO2 cartridges and mini pumps that take forever to inflate or leave you stranded the nanoFumpa is the solution for your emergency tire inflation needs.
