ProRollers bat rolling service is the first and ONLY company to use an approved compression tester on every bat and post pictures of before and after compression test results on our Instagram account.  (Click For Recent Pics)

And we don’t just do it once: We compression-test every bat we professionally heat roll TWICE. We test the compression before the rolling process so we know the starting compression of the barrel. Then, we put each bat through the heated rolling process individually and compression-test them again to ensure the process is complete.

Why the extra step? We want to ensure you are getting the best possible performance. Companies might tell you that your bat is broken in but how do they know? What measures do they take?

ProRollers knows that when it comes to getting gear game ready, the same break in level may not be right for everyone. Some people use their bats in leagues and games where there are bat restrictions or they compression test. This is why we offer 2 different levels of bat break in, Standard and ProMax. Compression testers are devices designed to test the current break in status of the barrel of the bat.  This testing shows the stiffness of the barrel and in certain tournaments bats can not test below a certain reading or they are deemed TOO HOT to use.  A bat that does not pass a compression test would not be allowed to be used in that specific event.  Compression testing is not common but we do give our customers options to fit their needs.  In our photo section and the pics posted online we have 3 cropped images.  The first reading is the stock form of the bat right out of the wrapper. The second photo is the bat compression test after our standard heated rolling service and all bats rolled to this spec will pass a compression test when they come from us. The third photo in the group is the lowest compression we can get on the bat and balance performance and lifespan. Bats rolled to this max spec will not pass any compression testing,  but will perform to their max level right away.

Our Standard Heated Bat Rolling Service includes a compression test of the bat right away so we have a reference point of the current stiffness. A compression tester is a device with a gauge on it.  The bat is placed in the tester to determine the current break in state.  We then put it through the process described above until the bat is within 15-25 psi on the appropriate gauge. When pushing the bats to this mark, it ensures the bat is through its dead phase and is performing right up to the max factory guidelines and still on the passing side of a compression test when they arrive.  This standard service will deliver a game ready bat and continue to break in naturally.

Our ProMax Performance Heated Bat Rolling Service includes all the services above but we proceed to push the bat to the upper levels of performance past the passing specs on the appropriate gauge. When we do this the bat will perform at its ultimate performance and will not pass a compression test if performed on the bat. A bat that does not pass a compression test would not be allowed to be used in that specific event.  This service does take nearly twice as long as we do need to test the bat multiple times throughout the process to ensure it is broken in without breaking it, it is a fine line with delicate testing instruments. When your bat comes back with this service performed it should only be used in home run derbies and showcase events as it does not comply to any sanction rules. It will also be a firestick like you have not swung before.
