Versatility and Advantages
Also available in the innovative technical solution RRAH (Reversible Ring on Aluminium Holder): one spinning ring with 2 flanges and one aluminium holder with a cut.
Less weight: the ring and the holder have a minor weight (about 30-40 grams) than the solid ring, which means less power consumption for the ring frame;
Double ring life: the ring can be used twice, since it has 2 flanges. When the first one is over, the ring can be flipped in order to use the second flange;
Unlimited life of the holder. No problem in the ring fitting: the holder replicates exactly the fitting part of the ring;
Saving on future costs: these reversible rings are lighter and less expensive than the full steel rings;
