ROCKBROS JG-PB-004 bomba de mano ligera para bicicleta con manómetro - negro

Pushing 120 PSI into your tyres has never felt this effortless—the ROCKBROS JG-PB-004 weighs just 110 g, yet its aluminium-alloy barrel delivers road-ready pressure in seconds.

Overview

The ROCKBROS JG-PB-004 is a compact, high-pressure hand pump engineered for cyclists who refuse to carry dead weight. Its single-barrel design and direct-connect reversible head make inflation quick and hassle-free on Presta or Schrader valves. The integrated analogue gauge reads in both PSI and bar, so you can hit your exact pressure target without guesswork. A frame-mount bracket keeps the pump secure on your bike, and the dust cap protects the head when not in use. Whether you ride road, mountain, or hybrid, this pump is ready for roadside fixes and pre-ride top-ups.
