Product details

With the TurnOn Bunker SL, the name says it all: hermetically sealed against the harshest conditions you encounter on your wildest trail rides. Thanks to its one-piece shaft with a low stack height and titanium screws, it is particularly lightweight. The fully sealed construction of the TurnOn Bunker prevents dirt and moisture from entering, making it completely waterproof. Even during a rigorous underwater test, the Bunker proved its long-lasting impermeability and is certified to the high IP68 standard.

Also unique is the double air chamber system, which allows the seat post to extend and retract without drawing in air from the surroundings. This means the Bunker operates autonomously, effectively excluding contamination. Thanks to this design, the Bunker offers a long maintenance interval of up to 400 hours of use. The system automatically vents during operation for a consistently reliable function without sagging. An oil bath ensures that the Bunker is always well-lubricated. With "ActiveRide," the Bunker also features another unique function that provides safety and comfort. Impacts that directly hit the post are absorbed by ActiveRide in the range of 5 to 10 mm. This protects the spine in extreme cases, makes every ride more enjoyable, and ensures maximum riding comfort. Ride on with TurnOn!
