CO2 inflator with regulation system

Zéfal EZ Big Shot CO2 Inflator

The Zéfal EZ Big Shot inflator is the ideal tool for quickly reinflating your bike's tires, whether tubeless or tubetype tires. Made entirely of aluminum, this robust CO2 inflator is aimed at cyclists keen to save time during their outings. Its compact format allows it to slip discreetly into your equipment. For an integrated transport solution, you can opt for the Pulse Z2i bottle cage (ref. 1706) specially designed for this purpose. Featuring an auto-locking air regulation system, the EZ Big Shot provides precise control of tire pressure. Consult the usage table to choose the right cartridge for your tires and find out the maximum pressure you can achieve. The CO2 cartridge, made from 100% steel, is fully recyclable. Remember to throw it in the bin dedicated to recyclable waste.
