Suspensions in natural rubber, for Boiani plates. The set includes 4 high and 4 low rubbers (for a complete pair).
The hardness must be chosen based on the weight of the person using the plate:
col. red: soft, hardness 65A (<35 kg) / col. yellow: medium, hardness 75A (<50 kg) / col. blu: hard, hardness 85A (> 50 kg)
It is advisable to change the rubbers once the racing season is over, as they are materials subjected to many efforts and twists and over time the quality and performance for which they have been designed is highly reduced.
