Pro 500cc Storage Water Bottle
If you think seat packs are whack and loath loading up your jersey pockets with your emergency repair kit, the PRO storage bottle provides a clever storage solution.
It fits in virtually any water bottle cage and has a storage capacity of 500cc which is plenty of space for the essentials. Total height is about 5 inches and a wide mouth opening means easy access.
Make use of those unused water bottle cages. A great way to carry a spare tube, extra tools, CO2 cartridges, etc. I keep the heavier items in these instead of my pack. It keeps the center of gravity of the bike low and less strain on me from a heavy pack. These are a little smaller and is why I rated them a 4 not a 5.
