Introducing Topeak's TurboBoost technology. This 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.- Anodised aluminium barrel- Oversized padded handle- Stable aluminium and rubber base- SmartHead DX1 head- Extra long hose- Air bleed button for precise pressure setting- Head 'dock' holds hose- Easily inflates up to 200psi- Includes ball, air bladder needles
