Topeak Joe Blow Ace Review

JoeBlow™ Ace
Unique to the JoeBlow Ace floor pump is a revolutionary 2-barrel, 3-stage design. This switch activated, progressive filling action allows the user to optimize the pump’s output for high-volume and high-pressure applications filling each tire with less strokes.
Stage 1 opens both barrels for the higher volumes needed to start the inflation process on all tire types or for filling mountain bike and other high volume tires.
Stage 2 engages the larger main barrel providing the high pressures needed for road bike and road racing tires and optimizes inflation up to 120 PSI.
Stage 3 engages the smallest barrel for the ultra-highest pressures required for track racing tubulars and optimizes inflation up to 260 PSI.
Although the JoeBlow Ace can reach extremely high pressures, it’s not recommended for use on rear shocks or suspension forks.
