Ski equipped with variable length elastic transmitters on either side of the binding zone

A ski comprising:

• an elongate beam having a central arched portion of a predeterminate length (LC) between a forward contact line and a rear contact line, an upwardly turned front portion comprising a shovel and a less turned up rear portion comprising a tail, said central portion comprising a binding mounting zone corresponding to a standardized zone,
• two transmitters located in said central portion and each on either side of said binding mounting zone;
• one of the ends of each transmitter being connected to the beam by a complete connection;
• the other end of each transmitter being connected to the beam by a partial connection means, free in translation along a longitudinal direction, the partial connection comprising one of an elastic and viscous element that resists the longitudinal displacement of said transmitter;
• a portion of a length (l.sub.T1, l.sub.T2) of each transmitter between the two connections being left free at least in translation with respect to the beam;
• the ratio of the free length (l.sub.T1) of a front transmitter over the free length (l.sub.T2) of a rear transmitter being comprised between 1.5 and 2.5, and the ratio (l.sub.T1 +l.sub.T2) over a ski length (LC) being, comprised between 0.15 and 0.25.
