Click on FORUM at the top left of the page. When you get there on the left side you will see a site called
bowlingball.com. Click on that and it will show you a topic that says bowling balls. Cover that with your mouse and pick any bowling ball manufacturer. Pick any bowling ball and click on that. It will give you a description of the ball and where it says the RG of the ball click on that and it will give you what RG means in a ball and what the scale for RG is from low to high. Hope this helps thoise not familiar with the term RG of a bowling ball.

Nice summary! I had a hard time understanding it at first.

Instead of going to bowlingball.com, here is what the links to the RG show:

Bowling balls have a RG (Radius of Gyration) converted to a scale of 1-10. RG numbers range from 2.460 to 2.800, but some companies have converted them to a 1-10 scale to help give the consumer a better frame of reference. Mass distribution numbers describe the distribution of mass in the bowling ball. High RG numbers indicate that the balls mass is distributed more towards the cover (cover heavy) which promotes length through the heads of the bowling lane. Low RG numbers indicate that the balls mass is distributed more towards the center (center heavy) which promotes an earlier roll through the front part of the lane.
