The Topeak Mini G MasterBlaster isn’t a half-pint porn star from the Bronx—rather, a mini pump ready to tackle any trailside tire change with ease. The Mini G MasterBlaster feature special internal valves that engage the compression chamber on both the push and pull actions to double the volume of air moved on each stroke, so 50 pumps just became 25. The durable aluminum barrel survives the worst of diggers, and the 145psi capacity allows you to stop and fill a roadie’s tire on the ride back to your house—without making you late for dinner.

  • Easy-to-read gauge for precise inflation
  • Mounting bracket frees-up pocket space
  • Dust cap protects pump head from the elements
  • Dimensions: 10.8 x 1.5 x 0.7in (27.4 x 3.8 x 1.8 cm)

I feel lame asking this, but do I need an additional adapter also? I carried this thing with me all the way across Iowa (RAGBRAI) without needing it (lucky me!!) but was never sure if I had all the pieces.
