Elite’s CRONO HYDROMAG is the first hometrainer in the world that combine both the magnetic and fluid technology. The combined action of the two forces are at the basis of a trainer that has uncomparable performances concerning range of regulation and smoothness of the pedalling. Supplied with a large diameter Elastogel roller (45 mm), which allows to obtain a greater adherence with the tyre and less turns with subsequent reduction of noise level 50% superior compared to a trainer with aluminium roller, and also a prolonguing of product’s life and a 20% reduction of tiire consumption.

The HYDROMAG unit is a device that exploits the resistance caused by the rotation of discs that rotate at high speed in n oil-filled seating. The movement of one of the discs in which the permanent magnets are fixed generates the resistance variation at the same speed. This operation is controlled by a graduated shift lever, with five positions, that is fixed to the handlebar of the bike with a quick clamp.

The resistance unit is built in an aluminum alloy with its proper fins for the sqaundering of heat that maintain a low temperature of the device. The dimensions and the geometry of the resistance unit are the result of a series of tests carried out with the help of the proper electronic equipment, that allowed to evaluate the behaviour of the system at all different resistances and speed. The oil used has particular carachteristics of viscosity and thermal dilation that make ininfluent the temperature variation on the resistance given. The system uses also the resistance of some neodymium magnets fixed around an iron disc that rotates at high speed. By acting on the position of this disc compared to an aluminum disc fixed on the shell, it is possible to obtain the resistance variation given by the difficulty of the aluminum disc to “cut” the magnetic flow and the increase of the rotating surfaces in the oil. The perfect balancing of the rotating masses and the quality of materials used guarantee the decrease of vibrations and increase of trainer’s life.

The resistance regulating system allows to train with a lower effort level during the warming up phase and with a bigger one during strengthening. All of this can be obtained without sprints in spite of the wide spacer between minimum and maximum resistance.

Another important feature of this unit is the absolute progression that can be obtained in the passage between one level of resistance and the other, maintaining a roundness of pedalling typical of a road race.

Another very importand innovation of the Crono Hydromag is the frame which compass self-regulating structure allows to transmit the load on the resistance unit in function of the weight and position of the athlete, differently from what happens with a classic kind of frame, where such load is pre-determined by a mechanic system with constant load.

It is also possible to upgrade the trainer by using the Plus Unit Hydromag which visualizes 15 different kind of information:

* Current speed
* Current power
* Current slope
* Elevation Gain
* Race time
* Race distance
* Average speed
* Average power
* Average slope
* Maximum speed
* Maximum power
* Total distance
* + / - indicator (it indicates if the current speed is higher or lower than the average one).
* Indicator of the position of the command lever of the resistance.
* Battery off.
