2 in 1 Air Pump - Dual mode operation: twist the locking lever to switch between high volume HV mode for faster tire inflation and high pressure HP mode for higher pressure with less air output. It performs two separate operations of a bicycle tire pump and a high‑pressure shock pump. - Powerful and readable: Maximum 300 PSI / 20.7 (units). Features a clear and easy to read 1.5 in indicator gauge with PSI and rod reading. Lower pressure mode provides tire pumping capability. - Compatibility and accessories: Includes adapter 9.84 for use with compatible valves and connections, making the pump versatile for different setups. - Practical design: Simple to use with a two‑function design for cycling tires and suspension components, eliminating the need for multiple pumps. - Use scenarios: - Road and commuter bikes: quickly inflate tires to the recommended PSI with HV mode. - Mountain bikes: adjust tire pressure for better grip and control, using HV for faster inflations or HP for precise tuning. - Bicycle suspension: set up air shocks or forks by switching to HP mode for high‑pressure inflation and accurate readings. - Durable, reliable operation: straightforward mechanism, readable gauge, and included adapter enhance everyday maintenance and on‑the‑go adjustments.
