Compared to commercial rubbers kits:
- Greater power guaranteed over time
- Longer rubber life
What makes Roisub Rubber Kit so special?
At the heart of our innovation is the exclusive D.S.D. calibration process. (Durometer, Suspended Load, Dynamometer), a real revolution by Roisub, in the process of calibrating tires for spearguns.
The result of over 10 years of optimization, this pioneering technology ensures unprecedented precision and shooting power, as it does not simply consider the hardness of the rubber (detected through the Durometer test), but above all precisely determines its Hysteresis (Suspended Load Test and Dynamometer Test), thus managing to make it work at Maximum Yield without exceeding the “critical point” beyond which performance degrades.
Our kits are not just a replacement; they are a guarantee of performance, resistance and durability that only Roisub can offer.
With the Roisub Circular Rubber Kit, you can change the rubbers of your TRADITIONAL speargun, both single-rubber and double-rubber
The DSD process is a Roisub certified exclusive, designed to provide you with the best performance in every use.
The rubber used to make the kit is the rubber: ROISUB SPRINT Diameter 16mm.
How should I take measurements for the rubbers of my Speargun?
- The measurement of the mono-rubber is taken from the center of the hole in the head up to the last fin of the shaft.
- The measurement of the double rubber is taken from the center of the hole further forward in the head up to the last fin of the shaft.
