MIZUNO CRBN1 Review

AT A GLANCE

The Mizuno CRBN1 has a long reputation as a bat that Power Hitters have selected year after year for its consistent power performance, durability and affordability. This one-piece bat, in -8 and -9 drops, enables strong hitters to leverage their natural strength with maximum direct energy transfer and a slight end-loaded design that brings more barrel mass to the ball. This creates good exit velocity when the Power Hitter extends her arms and drives the ball.

• Stiff, one-piece bat provides good direct energy transfer leveraging the hitter’s raw power

• Slight end-loaded design brings a bit more mass toward the end of the barrel

• Overall construction results in good exit velocity when the CRBN1 is squared up

• Very large sweet spot lets Power Hitters maximize exit velocity on off-center hits

• Best fit for aggressive Power Hitters with good bat swing speed when using bats with -8 or -9 drops

• The Coach’s pick as one of The Top Fastpitch Softball Bat for Power Hitters

The CRBN1 consistently provides top power when the Power Hitter extends her arms in a hard swing. Power Hitters can count on the Mizuno CRBN1 large sweet spot and predictable output (exit velocity) every at-bat in every game, all season long. This power shows up as:

Power & Exit Velocity

Strong Power Hitters who attack pitches, generate good bat speed and swing with a slight uppercut will get the most out of this composite barrel - and get it consistently. And hitters who frequently hit off-center pitches softly will find themselves hitting more balls hard that used to be weak flyballs or mis-hits.

Swing Weight & Feel

The Mizuno CRBN1 bat is not a full end-loaded bat. It swings lighter and a bit smoother than the Easton Ghost Unlimited. Accordingly, lesser-strength Power Hitters may find it easier to maximize their personal bat swing speed with the CRBN1 while strong Power Hitters may find themselves pulling the ball foul with greater frequency. Because of its one-piece design, the CRBN1 will provide strong “stinging” vibration on mis-hits or in cold weather so strong hitters will have to tolerate it and/or wear batting gloves to mitigate the sensation.

Sweet Spot & Forgiveness

For a power bat, the CRBN1’s sweet spot is very large. This means Power Hitters will see more balls carry further rather than watching off-center hits become short, lazy flyballs. This helps “middle-of-the-order” hitters be more productive for their team.

Break-in & Durability

The Mizuno CRBN1 requires a short break-in period of 1+ batting practices (25-50 swings rotating the barrel 1/4 turn after each hit). After the break-in period:

Durability feedback on the Mizuno CRBN1 is mixed. What we consistently see:

• Holds up well for Power Hitters with clean contact

• Bat fatigue starts to set in by the end of one season of play

• Barrel response improves

• Exit Velocity stabilizes

• Feel becomes more predictable

The Mizuno CRBN1 bat is not ideal for Contact Hitters or Slap Hitters (or younger players) who struggle to generate enough bat swing speed with even slightly end-loaded bats. They will swing late and even solid hits will feel “dead”. Also, younger players may get discouraged from the “sting” they may feel from mis-hits or in cold weather.

FINAL VERDICT

The Mizuno CRBN1 is a proven power bat with a long track record for consistently good exit velocity and a forgiving sweet spot, enabling hitters to hit more balls hard. With its durability and affordability, the Mizuno CRBN1 combines performance AND value.

Price vs. Value

At a relatively affordable Price (MSRP) of $350.00, the Mizuno CRBN1 makes sense for all Power Hitters as follows:

You ARE paying for:

• Direct Energy Transfer of the Power Hitter’s natural strength and a bit more barrel mass to reach max power output (exit velocity)

• A large sweet spot

• Consistent barrel response

• High-end composite performance

• Good durability expectations (hopefully)

You ARE NOT paying for:

• Balance to maximize bat swing speed or control to better adjust swing plane mid-pitch

• Enhanced vibration control (“stinging” reduction)
