Lightweight and integrated, our iS (Integrated Storage) Cache Cage is designed to keep you moving in the event of a trail side mishap. An inflation device, multitool (with chain tool) and bottle cage are all integrated into one unit, there for when you unfortunately need it. The Cage features a neat flippable wing so it can be set for left or right hand users (or reversed for Seat tube mounting). The design is side entry so it will fit in tight spaces on full suspension frames and it's lightweight so you can use it on your cross-country race bike. It's also designed to work perfectly with the Scott Spark which features a recessed section on the downtube. The multi-tool features 8 forged and machined bits and we've added a corrosion-resistant coating for longevity and protection. The slim chain tool mounts to the multitool for maximum weight savings and ease of use. The CO2 unit is our Boundary CO2 delivery system which offers a fast and efficient method to reinflate your tire in an emergency. The valve is protected to avoid accidental engagement and our design allows you to easily control the rate and flow of CO2. The pack contains a 16g cartridge, but is also compatible with 20g cartridges.
