    Question for marucci

    Posted by IB on May 17th 2018

    What is the difference between a traditional barrel and a medium barrel. I’m trying to decide between the jb19 or rizz44

    **Official Response from Marucci**
    The RIZZ44 features a slightly thinner handle and taper to the barrel, whereas the JB19 is thicker through the taper and handle. Please see Chat Now function below to speak directly to a Customer Service team member. Thank you.

    Good Bat

    Posted by David on Apr 19th 2018

    I purchased this bat for my 14 year old son. While the bat is good I was not happy with a few paint runs on the end of the bat. I emailed customer service when we received it over a week ago and they have not responded to me. I have followed up with them 2x. With the cost of this custom bat , you would think that there would not be any paint runs and customer service would get back with you.

    **Official Response From Marucci**
    David, sorry to hear about the paint runs on your bat. Customer Service has reached out to find a solution to this issue. Apologies for the delay.

What is a Smart-Ready Knob?

Marucci’s Smart Bat technology allows Diamond Kinetics’ SwingTracker sensor to be securely fitted inside of the actual knob of a Custom Pro Model bat. By selecting Smart-Ready knob, you’re authorizing Marucci’s wood production team to carve out part of the knob and install a dual-locking mechanism to firmly hold your SwingTracker sensor in place, allowing for the most accurate data possible.

Don’t forget the sensor!

The Diamond Kinetics SwingTracker sensor captures your most precise swing data using 11 different metrics in four core swing categories: speed, power, quickness, and control, then sends it to the SwingTracker app through a paired iOS device via Bluetooth. View metrics in easy-to-read graphics and charts or sync with a unique 3D image or video of your swing.
