The Topeak AirBooster G2 combines precise tire pressure measurement with fast CO₂ inflation in one compact tool. Featuring a built-in 1½-inch analog gauge, it accurately reads up to 160 PSI / 11 Bar while allowing fine flow control to avoid over-inflation. The angled SmartHead fits both Presta and Schrader valves securely, and its dual-end body doubles as convenient storage for one threaded 16 g / 25 g CO₂ cartridge. Constructed from durable engineering-grade polymer, this inflator delivers reliability, portability, and ease for road, gravel, and MTB riders alike.
