Introducing the future of game-time adjustments, the CF-XD (-10) fastpitch bat engineered with the Adjustable on Demand Knob.

CF-XD TABS

It’s a very common practice for hitters to “choke up” in the batter’s box.

Choking up decreases the length of the bat which allows players to increase bat speed, shorten their swing, and gain inside plate coverage and control. The tradeoff is a significant loss of power because the player’s hand is no longer positioned properly on the knob.

Choking up is especially common with young players who have been provided the wrong size bat, which can impact their swing mechanics and hinder development.

The D-LAB set out to develop one bat with an adjustable knob that creates multiple bat lengths. This advancement will mitigate the loss of power associated with choking up.

The first solution involved a removable knob, a second attempt leaned on three interlocking components—both proved to be too cumbersome and time-consuming for in-game situations.

The idea that knocked it out of the park? We created a sliding and locking knob. One simple component that could move along the bat’s handle—no additional tools or equipment.

Our engineers built hittable prototypes using 3D printers. We’d take the bats to the cages, get player feedback, refine and repeat.

After hitting nearly 20 prototypes we landed on a final design that found the balance of performance, ease of use, and safety. The CF-XD was ready for action.

By creating an adjustable knob, players can better control the MOI of their bat—experiencing all the benefits of choking up while minimizing loss of power.

  • MOI reduces by 5% per 0.5 inch of bat length change which translates to a 10% reduction for 1.0 inch.
  • This technology requires 7–10 lbs. of force to lock and unlock the knob and was tested at multiple age levels to ensure the knob was functional for younger players.

Introducing the first fastpitch bat featuring an AOD (Adjustable on Demand) Knob, the 2019 DeMarini CF-XD (-10).

AOD Knob

The Adjustable on Demand (AOD) Knob completely redefines what a bat can do. This game-changing technology enables batters to make real-time adjustments at the plate. Whether choking up or extending the bat length for more plate coverages, hitters can maintain their normal swing mechanics while minimizing power loss.

  • Adjustable in half inch increments (0 inch, 0.5 inch and 1.0 inch)
  • By changing the bat’s effective length, the AOD Knob allows players to change the bat’s MOI (Moment of Inertia)

PARAFLEX+ COMPOSITE

Our new Paraflex+ Composite is cured for consistency. By exposing the barrel to the perfect temperature for the perfect amount of time, we can ensure the most dependably responsive barrel imaginable.

3FUSION SYSTEM

The next generation of D-Fusion technology. Streamlined design allows for greater weight control and feel while continuing to reduce vibration and redirect energy back into the barrel. The 3Fusion Endcap works as part of the 3Fusion System to optimize bat weight control and performance.

  • Just because something has always been done a certain way doesn't make it right. At D-LAB, we're writing the next chapter in bat technology with the 2018 CF-XD Fastpitch Bat. 

    Our all-new Adjustable On Demand (AOD) Knob allows hitters to make in-game adjustments at the plate, either shortening or extending the bat length - depending on the situation. This means you maintain normal swing mechanics and mitigate power loss associated with removing your hands from the knob. Paired with our new Paraflex+ Composite and 3Fusion™ System, the technology in this bat pushes the limits further than ever before.

    D-LAB is where R&D reigns free and Ray DeMarini’s vision comes alive. Where we defy norms on the daily with bats no one else is brave enough to build. Bats born in the D-LAB aren’t made for the masses, they’re made for the players ready to unlock potential even they didn’t know was possible.
