Co2 tire inflateor its very small and uses stanard co2 for a bb gun. Got it at my honda dealer for about $17 has been very handy many times for myself and people i found on the trail. And i always keep a few tire plugs and the plug tool.
Yeah, but don't drink them while your riding and don't forget a first aid kit too!Enought beer for yourself and the other guy who is to cheap to buy there own.
