A Heavy ring is 8 grams heavier than a normal ring. Add 16g to the total mass of the diabolo!

The Stability Ring is an innovation from Sundia that gives unmatched stability in diabolo. It is made of telfon material that is slippery to insure very low friction with the string and therefore it allows the diabolo to be spinning for longer. Comptatible with EVO G2 diabolos and sold by pair.

Heavy ring weight : 14g 

Normal ring weight : 6g
