ROCKBROS Mini Bike Pump & CO2 Inflator — 2-in-1 Hand Pump, 5.5in Aluminum, Presta/Schrader

ROCKBROS Mini Bike Pump Hand Pump & CO2 Inflator 2-in-1 is a compact, dual-mode tire inflator that works as a manual hand pump and a quick CO2 inflator for fast, high-pressure top-offs up to 110 PSI.

This lightweight, travel-ready pump blends a CNC-machined aluminum hand pump with an integrated CO2 inflator head, accepting both Presta and Schrader valves. At roughly 5.5 inches and 0.16 lbs, the unit fits into saddle bags or mounts to a frame with the included bracket. It’s designed for cyclists who want a small, durable tool for roadside fixes that saves space without limiting functionality.

How do I switch between hand pump and CO2 inflator modes?

Switching modes is intuitive: use the hand pump mechanism for controlled inflation and engage the CO2 head when you need a rapid pressure boost. The same unit houses both systems so you can hand-pump to a safe pressure and finish with CO2 for high PSI required by road tires.

• Turn the threaded pump head to connect to Presta or Schrader valves.
• Pump manually until near target pressure, then attach a CO2 cartridge to the inflator head for a quick top-up.
• Soft sponge sleeve reduces cold transfer when using CO2 cartridges (cartridges sold separately).

Will this pump fit my bike’s valve stem?

The ROCKBROS pump uses a convertible head that works with both Presta and Schrader valves, removing the need for extra adapters. That makes it compatible with road, gravel, hybrid, and many mountain bike tubes and tubeless setups when used with the appropriate sealant/procedure.

• Integrated valve convert design handles Presta and Schrader sizes directly.
• No separate Presta converter required for compatibility.
• Secure threaded connection prevents leaks during inflation.

How portable and durable is the pump for everyday rides?

At just 5.5 inches long and about 0.16 lbs, the pump is extremely portable and designed to be carried daily. It’s CNC-machined from aluminum alloy for strength and precision, so it stands up to regular use without adding noticeable bulk.

• Compact size fits in saddle bags, pockets, or mounts to the frame with the included bracket.
• Aluminum alloy construction resists damage from drops and vibration.
• Non-slip threaded handle improves grip during manual inflation.

How easy is it to use under pressure on a ride?

The pump balances simplicity and speed: the hand-pump function gives controlled inflation when accuracy matters, while the CO2 mode provides fast, high-pressure fills. Ergonomic touches like the non-slip threaded handle and insulated sponge sleeve for CO2 operation make it practical during roadside repairs.

• Quick-connect head reduces fiddling when changing valves.
• Insulated sleeve protects fingers from cold when releasing CO2.
• Mounting bracket keeps the pump accessible and secure on the bike frame.

Who this is for: Cyclists who want a minimal, reliable inflation tool for rides — commuters, road riders, and mountain bikers who prefer to carry a single compact solution. It’s ideal for anyone needing both controlled manual inflation and the speed of CO2 top-ups without packing multiple tools. Note: CO2 cartridges are not included; bring cartridges separately for CO2 use.
