CRONO FLUID from Elite is a sealed hydrodynamic system that regulates the effort of the pedalling through a rotor submerged in oil with special carachteristics of viscosity and high temperature resistance. System’s rotation speed determines the effort, more or less intense that is transmitted to the wheel. Everything happens inside an aluminium alloy housing, with wide cooling fins for a quick heat squandering. These are the advantages of this kind of unit:

* The easiness of use, no regulation of the effort is necessary because it self-adjusts with the variation of speed. You just have to use the gears of the bike, as when you are on the road to obtain different levels of resistance.
* The roundness of pedalling, much alike a road race;
* A greatly progressive resistance;
* The elastogel roller, which in this roller has bigger dimensions (45mm of diameter instead of the usual 30mm). The elastogel material allows to obtain a perfect adherence to the tire allowing progressions of the pedalling rythm without noticing any slipping between the wheel and the roller itself. Notably one of the most underlined limits of the old rollers was the poor adherence to the tire that blocked the change of pace and effort like it naturally happens on a road race.

Another very important innovation of the Crono Fluid is the frame which self-adjusting compass structure, that allows to transmit the load on the resistance unit in function of the weight and the position of the athlete, differently from what happens with a classic frame, where such a load is pre-determined by a mechanic system with constant load therefore the weight of the cyclist does not affect the development of power.

The result of such innovation is that the power of the pedalling is a function also of the weight of the cyclist, with a greater level of faithfulness to road race that is 51% superior compared to a classic frame. The comparative tests carried out in the laboratories of the Mechanical Engineering Dept. of Padua’s University show that on a road race the power expressed by the athlete is connected also to the weight and the position of the athlete as it happens only by using hometrainers that have a Crono frame.

It is not necessary anymore to regulate the pressure of the roller of the resistance unit on the tire or connect and disconnect the unit before and after the training. This system allows the rear wheel of the bike of any dimension to lean on the roller of the resistance unit automatically with the weight of the bike itself and the cyclist, moreover the slightly flexible system reduces the effect on bike’s frame and simulates more accurately the feeling of a road race. Crono Fluid is widely known as the most silent, smooth and easy to use trainer on the market.
