## What do the specs on a bowling ball mean?

With that being said, the lower the RG number the earlier the hook. Just the opposite with High RG, the higher the number the more length you will get out of the bowling ball. Stated earlier, Differential is the number that tells us Track Flare Potential.

## What does RG and differential mean in bowling balls?

In short, the RG of a bowling ball is an account of the location of that mass inside the given bowling ball. Differential of RG is the difference between the maximum and minimum Radius of Gyration. RG-differential indicates the bowling ball’s track flare potential.

## What is low Rg for a bowling ball?

Radius of Gyration (RG) – An account of the location of the mass inside a bowling ball. Rg tells us whether the ball has the mass toward the center of the ball (low rg), toward the cover of the ball (high rg) or somewhere in between (medium rg). Low rg balls rev up quickly.

## What does RG mean on a bowling ball?

## What is a urethane bowling ball?

## What is RG value?

The Rg represents the root mean square distance of the molecule’s components from the mass center of the molecule. The single Rh and Rg numbers generated by a GPC/SEC analysis are the weight average values obtained from compiling the calculated values at each data slice.

## How do I choose a bowling ball core?

Some say your ball should be approximately 10 percent of your body weight, up to the maximum 16 pounds. Most pro bowlers use 16-pound balls, although more than you think use 15-pounders. Another method is to add one or two pounds to the weight of the house ball you normally use.

## How do bowling ball sizes work?

A bowling ball should weigh 10 percent of your body weight (up to 16 pounds), which means you really shouldn’t be grabbing, say, an 8-pound ball if you weigh 150 pounds.
