Tija Thudbuster

Acabo de descubrir la KTM alp challenge

y me ha llamado mucho la atención la tija, que consiste en un cuadrilatero articulado con un elastómero "dentro".

No tengo ninguna intención por ella, pero si alguien la ha probado tengo curiosidad en saber qué tal le ha ido.
Por supuesto que según ellos funciona de pm...

Will the seatpost interfere with pedaling the bicycle?

No. The patented design uses a downward/rearward motion to isolate the suspension movement from the drivetrain of the bicycle. The seatpost is actively absorbing bumps regardless of whether you are coasting along or really cranking on the pedals.

Will the downward/rearward motion affect handling and control as the seat moves toward the rear wheel?

No. The downward/rearward motion is quite natural and actually increases control in rough terrain. As the rear wheel hits a bump, a rigid seatpost tries to lift the saddle up and forward, pitching you toward the handlebars. With the Thudbuster, this up-and-forward lift is counteracted by the down-and-back motion. The rider is unaffected by the bump. The rider's weight also stays on the rear wheel to help maintain traction during the bump encounter. By comparison, a rigid seatpost not only pitches the rider toward the handlebars, it also shifts weight off the rear wheel, causing a loss in traction, and loads the front wheel, which can be dangerous in rough terrain.

Los elastomeros funcionan bien, pero con el tiempo se endurecen y es probable qu haga ruidos raros, habria que ver el precio del recambio del elastomero.
