Here is the Topeak Twinturbo technology, a new concept of floor pumps that will save you up to 50% of time and effort. For over 25 years, Topeak engineers have had a dream in mind. Create the definitive floor pump. It must have a high pressure air exit and a huge volume delivery to fill both road tires and MTB in a simple and efficient way. Twinturbo technology uses the traction and push of each blow by transferring LAir between its two cylinders. Pulling the handle towards L’Alto moves a huge amount of air volume from the largest cylinder to the smaller one. Pushing the handle downwards compresses L’Air in the smallest cylinder in a high pressure exit that fills road tires with high pressure or MTB tires with great volume. It doesn’t matter the type of tire, JoeBlow Twin Turbo will literally jump away.
