Small but super handy! The Micro Rocket Carbon from our friends at Topeak is so incredibly light, you’ll wonder if it will work. And yes, it does work and very well we might add! At a mere 55 grams, this dynamo will pump your tires up to 160 psi in no time flat. It comes with a mount bracket and easy release rubber strap, though at 6.3 inches long, it’s small enough to just pop in your pocket or pack for those just in case situations. Another smart feature is the integrated dust cap that keeps gunk from collecting in the head so it’s always ready to go. For a sleek-looking, lightweight pump, go with the Micro Rocket Carbon!
