The FusionK2 system is the evolution of the FusionK1, with the addition of a pair of rubbers on the handle side, it increases power and the use of heavier 7mm diameter shafts. It is a two-load system and is dedicated to more targeted fishing for larger prey and longer shots. Thanks to the reverse movement of the tires (common to all Roisub systems) recoil and accuracy are taken to the highest level.
Compared to Fusion/FusionK1:
- SIMPLICITY: loading requires an extra step, it is similar to the traditional double rubber
- BRAND: minimal difference despite using an extra pair of tires since the tires remain lateral to the shaft and in close contact
- POWER: greater in fact requires the use of larger diameter rods (+30%)
- PRECISION: similar but requires a firmer wrist
- RECOIL: greater recoil compared to Fusionk1 (+20%)
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.
The DSD process is a Roisub certified exclusive, designed to provide you with the best performance in every use.
