Cabrinha Crosswing X2 4m , In good condition just been upgraded to the newest model , great wing size for 65-80kg riders with 2 mini booms for easy adjustment and control As the sport of Wingsurfing is literally taking off, its range of use is getting exponentially wider. The all new Crosswing X2 follows the sports leap in performance to provide cutting edge features not seen in other wings. The Crosswing X2 has an all new body outline and inflatable frame which makes it incredibly stiff and rigid. The wing holds its shape while under heavy loads or while boosting massive airs. The control factor has been upped in many important ways. First off, we've fully separated the air boom inflation from the leading edge inflated section. This allows us to properly pressure each section individually to achieve the X2's incredible stiffness while in flight. We've then taken that concept one step further with our unique Double Strut technology. The Double Strut of the X2 allows one inflated mini strut to support the canopy profile while the second "boom" strut is designed for precise ergonomics and predictable wing control. Each strut serves its own function and purpose without compromise.
