For over 25 years, Topeak engineers have had one dream in mind: to create the ultimate floor pump. Topeak may have finally hit the nail on the head with the Joe Blow Twin Turbo. It must have high pressure air output and massive volume delivery to fill both road and MTB tires easily and efficiently. TwinTurbo technology utilizes the pull and push of every stroke by transferring air between its two barrels. Pulling the handle up moves a massive amount of air volume from the larger barrel into the smaller barrel. Pushing the handle down compresses the air in the smaller barrel into high pressure output that fills road tires with high pressure, or MTB tires with large volume.
