Mini bomba elétrica ROCKBROS 42320008001 para válvulas Schrader/Presta 100 PSI - Preta

Getting stranded with a flat tire miles from home is a cyclist's worst nightmare. The ROCKBROS Mini Electric Pump eliminates that fear, delivering up to 100 PSI of automatic inflation for both Presta and Schrader valves in a pocket-sized aluminum body. No more manual pumping on the roadside—just set your pressure, press start, and let the rechargeable lithium battery do the work.

Tips

For best results, attach the pump directly to the valve and keep it upright during inflation to avoid strain on the valve stem.
