Telescopic Barrel CNC Machined Mini Pump

Last updated 2026-09-06

This mini pump features a unique telescopic barrel design that maximizes air output with every stroke, making it highly efficient for mountain bike tires. The all-metal construction is CNC-machined for precision and durability, ensuring it can handle the rigors of off-road use. It is specifically optimized for pressures up to 80 PSI.

A secure valve lock mechanism ensures a tight seal on both Presta and Schrader valves, preventing air loss during the pumping process. This feature is crucial for maintaining efficiency when using a smaller portable pump. The compact size allows it to be easily tucked away in a pocket or attached to the frame using the provided bracket.

Manufactured in Taiwan, the GM043 model emphasizes quality engineering and robust materials. The telescopic action allows the pump to remain small for storage while providing a longer stroke for faster inflation when needed. It is a reliable and stylish choice for mountain bikers who need a dependable manual inflation tool.
