2021 Mizuno PWR CRBN Review

Name: 2021 Mizuno B21-PWR CRBN
Brand: Mizuno

By Bat Digest | Last Updated December 8, 2020

Our hitters love the huge, can’t miss barrel. They also like the sound of the bat. It has a flexible connection a lot like DeMarini’s CF—hitters who like that feel will like the Mizuno PWR CRBN.

2021 B21-PWR CRBN Models

The 2021 Mizuno PWR CRBN is a big barreled, two-piece composite bat with a mostly balanced swing and a more reasonable price point than other two-piece composites. If you’re in the market for a two-piece composite bat, are comfortable with the idea that all BBCOR bats are basically the same, and want to save a few bucks on a new bat, then the Mizuno PWR CRBN could be for you.

The 2021 Mizuno PWR CRBN in BBCOR has a MAAASSSIVE barrel. It has the largest barrel profile of all BBCOR bats---just a bit bigger than the Easton Maxum Utlra. It swings right between the balanced and balanced+ group. So, in other words, on the verge of feeling a bit heavy, but not that bad. Our hitters were impressed by the big barrel, wish the connection piece was stiffer, and liked the Exit Speeds on this can't miss barrel.

Construction

The 2021 Mizuno Power CRBN is a two-piece composite bat with the biggest BBCOR barrel in the game. There is a lot of marketing jargon associated with the parts of the barrel. For example, they call the barrel the Detonator COR, the connection piece the Dual Frequency Damper, and the grip a Speed-Helix Grip. We aren’t capable, or interested, in understanding what these materials actually are. In the end, it’s a two-piece composite bat with a big barrel and a slightly higher than average swing weight.

Overall Ratings

The overall rating uses seven different weighted metrics to determine our overall score. Half of total rating comes from the player and our exit speed tests (Player Rating: 25%, Performance: 25%).The other categories are Relevance (20%), Demand (10%), Durability (10%), Resell Score (5%), and Tech Specs (5%).

(UR) Un Rated: An overall rating of UR means the bat has yet to be fully rated. When it is, this score will update.

(PlaRa) Player Rating: We measure player rating from user reviews. Those users include our own hitters that we test at the lab as well as reviews we find online.

(ExVe) Performance: Performance measures the exit speeds and distances we capture in our hitting lab with HitTrax using these bats.

(Relv) Relevance: We measure the number of sizes and the MOI of the bat. Bats with a wider range of options get a better score.

(Dmnd) Demand: Demand is measured by consumer sentiment and the buzz around the bat.

(Drb) Durability: A bat’s durability is measured by user reviews as well as feedback from manufacturers.

(ReSl) Resell Score: Based on the price the bats go for used. Higher prices mean greater user demand which means, generally, a better bat. A resell value closer to its original price means a higher score.

(Tech) Tech Specs: We rate the bat on its technological advancements from previous years and compared to the industry at large. This is our chance to reward companies who are trying to innovate.
MOI
MOI or Mass Moment of Inertia is a measurement of bat swing weight. This quantifies how difficult it is to swing a bat. The industry often refers to this as things like End Load or Balanced but those words have been overused to the point of meaninglessness. We measure the actual swing weights of each bat we test using the industry-standard pendulum period, balance point, and scale weight. You can read more about that here.
Price
The price is the original MSRP price of the bat.
Type
The types of bats are single-piece alloy (SPA), two-piece composite (TPC), single-piece composite (SPC), hybrid (Hyb.), and wood (Wood). Hybrid bats are made of composite handles and alloy barrles.
Date
The estimated date the bat began distribution.
