2023 Easton Maxum Review

By Bat Digest | Last Updated May 22, 2023

The 2023 Easton Maxum Ultra is patterned after the 2021 Maxum Ultra in a single-piece composite with a giant barrel and moderately light swing. It is the same as the 2021 version of the bat but only comes in a BBCOR and a 32 through the 34-inch length. Had it been more widely available, we’d consider it one of the best BBCORs on the market. Easton is not interested in making this bat its marquee swing, but we predict that one day it will be impossible to find. (USSSA hitters will have to go with the 2021).

2023 Maxum Ultra Models

We are fans, and everyone who swings it is a fan. In fact, the bat gets the best ratings on the site in the only place it can be purchased ( here). It’s a huge barrel, light swing, and an excellent feel for being a single-piece composite.


General Recomendations

We’d put this bat up in the top five 2023 BBCOR bats. But since it’s hard to find (only at and doesn’t come in a 31-inch, it’s hard to say its a must-get. But, if you want something off the beaten path that hasn’t been run over by the type train a few times, then check out the 2023 Maxum Ultra.

Price It

The 2023 Easton XXL is a single-piece composite BBCOR bat patterned after the 2021 Maxum Ultra. It's ag great bat but with very limited distribution (only on Easton's site). But, it really can pack a punch. We think Easton's push toward a more traditional three-bat lineup has left this bat super underrated.
Sizing: 32, 33, 34-inch
Release Date: January 1, 2023
Serial: BB23MX
Bat Type: Single Piece Composite
Barrel Size: 2 5/8

Comparable Bats

There are not very many single-piece composite bats out there. Your closest relative of the bat is JustBats Combat B2, which, and there’s a long story here, is the sister at of this Easton maxum XXL. Both come from the Combat labs of days gone by, but after a bankruptcy restructure, you can find this single-piece composite in an Easton line and a JustBats line. Weird, but it is what it is.

Previous Models

The bat, as far as we can tell, has no changes between the 2021 version and the 2023 version. Our guess is these are left over 2021 models that have been colored up for 2023 and then sold exclusively on Easton’s site.


The BB23MX baseball bat is a high-performance 1-piece composite bat from the Maxum series. It has a barrel diameter of 2 5/8 inches and a BBCOR certification, making it suitable for high school and collegiate baseball. The Flow-Tack Grip ensures a comfortable and secure grip while swinging. It’s similar to Lizard Skin, but it’s not. The bat is made of full composite material, which gives it flex and a light swing in a single-piece design. It was released in 2023 and comes with a 1-year warranty. This bat is designed for serious baseball players looking for a top-of-the-line composite bat with great performance and quality.

Marketing Writeup

Our best marketing write-up:

Introducing the Maxum Ultra from Easton, a 1-piece composite bat with an XXL sweet spot, offering a blend of speed and power. The bat has been designed based on player feedback, with increased mass in the barrel for added advantage. It features Seamless Carbon Construction, combining the stiff feel of a 1-piece bat with the smoothness of a composite. The Flow-Tack Grip offers superior cushioning and tackiness. Leading college programs use Easton’s BBCOR bats and have a successful history in the College World Series.

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%).

*: When a bat is denoted by a star (*) it is a preliminary rating. Expect it to be updated as we learn more about the bat and gather more data.

(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 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.
The price is the original MSRP price of the bat.
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.
