With pressure gauge:
Unlike other standard CO₂ cartridges on the market, the ROCKBROS bicycle tire inflator features a 160 PSI pressure gauge, allowing you to easily and intuitively read tire pressure. This allows you to monitor your tire pressure at all times and avoid overinflating. This truly is a safe solution for cyclists.

Fast inflation and rotation control:
Thanks to the CNC-machined aluminum control knob, you can precisely control the amount of CO₂ injected into the tire. The inflation process can be stopped at any time. The tire can be inflated in just a few seconds, making it quick and convenient, and avoiding the hassle of changing a tube on the road.

Portable, compact and lightweight:
The pump weighs approximately 80g (including accessories), and its compact dimensions (6.1 x 3.6 x 3cm) make it easy to fit in a saddle bag, jersey pocket, or backpack. For cyclists looking for a lightweight and compact inflator for travel, the ROCKBROS CO₂ pump is an excellent choice. The miniature design doesn't add any extra weight to your ride.

Compatible with Presta and Schrader valves:
The CO₂ inflator head fits both Presta and Schrader valves. It features a Presta nozzle that can be easily converted to fit Schrader valves. Its robust construction ensures durability and a leak-free seal. Ideal for quickly inflating tires on mountain bikes, road bikes, and mini bikes.

Perfect fit for all threaded CO₂ cartridges:
The head is designed to accept all threaded CO₂ cartridge sizes (12g, 16g, 20g, and 25g). An insulating cover is included (for 16g cartridges only).
Note: Once CO₂ is released, the cartridge, head, and pump tip become very cold. To protect your hands, use an insulating cover. Do not touch CO₂ cartridges directly, as this may cause frostbite. Do not dispose of cartridges loosely. CO₂ cartridges are not included.

Installation instructions:

STEP 1: Place the insulating cover over the CO₂ inflator
STEP 2: Tighten the inflator until the metal needle pierces the cartridge
STEP 3: Attach the head to the tire valve to prevent leaks
STEP 4: Rotate the cartridge half a turn and start pumping
