Leki WCR TBS SL 3D 16 mm aluminum slalom pole is your perfect companion when fighting for that last hundredth of a second. The new Trigger 3D System offers more control through a direct connection between the gloves and poles. In addition, the ease of use has been improved for quick, simple click in and out and a larger release range through an innovative, three-dimensional triggering in which the triggering spectrum has been expanded four times. The Airfoil profile of the pole, based on the wings of an airplane, reduces the air resistance and optimizes vibration behavior. If you want to mount the Leki pole guard you need to have a new 3D insert.
