XLAB's Mezzo Cage Pod is a screw-top holder for your on-the-road tools and spares that fits in your bottle cage. It's convenient to move from bike to bike, it protects your gear, and it includes a fleece bag so the contents in the pod don't rattle and make noise inside. The pod is 750ml capacity to hold a spare tube, levers, CO2 inflator and multi-tool.
