MaxBat ProXR vs. Axe Style Handles

ProXR’s Round Knob is Key

ProXR was designed from the ground-up specifically for a rotational baseball bat swing. It reduces compression in the hands and gives batters improved performance. The ProXR is the only angled knob technology that uses a round knob shape to help create a smoother swing.

Axe Handles Utilize Oval Knob

The swing of an actual axe (chopping wood), which the competitors’ products are based on, has a linear swing path. Meaning it drives the hands to the point of contact. The oval shape locks the hands into alignment with the swing path. This PREVENTS the hands from deviating from that swing path.

3 to 5 MPH Increased Exit Velocity*

  • More consistent launch angles, 18° to 30°
  • Improved spin rate, 750 to 2000 rpm
  • Increased distance, 15 to 25 feet

* Results from professional players, your results may vary.

25% Compression Reduction

  • The ProXR reduced peak compression when the hands roll over the knob by 25%
  • Reducing possible Hamate injuries caused by traditional knob compression

The Speed Bump Effect

After intended contact, other knobs crash into the base hand - not ProXR, it provides a much smoother path.
