The Xlab Mini Cage Pod is a hard plastic storage container made with durable high density polypropylene material. It fits conveniently in a standard water bottle cage. The Mini Pod fits all Xlab cages and matches perfectly with the Xlab cage groove to prevent launching. Included with the pod is a micro fleece bag that protects the contents and muffles noise. It is completely water proof and will keep stored items clean and dry.There is plenty of room to fit a tube, tire levers, CO2 inflator and a multi-tool. This means the Mini Cage Pod can replace the traditional saddle bag for a cleaner looking bike. If you normally keep your flat repair kit in the jersey pocket, using a Mini Cage Pod can prevent jersey sag or let you use the jersey pockets for other items.
