Clack&Go™ technology:

an exclusive patent of Weissenfels, known and well appreciated for its amazing simplicity!

  1. Automatic tensioning system.
  2. Automatic centering.
  3. Ensure the perfect tightening of chains onto the tire just after the first spinning.
  4. Keep a reduced dynamic size while driving.

Their operation is very simple:

The mechanism inside the tensioner, consisting of a system of sprockets, constantly takes up any slack in the chain while the vehicle is moving, until the chain is perfectly positioned. This means that drivers can fit the chains and confidently continue their journey without having to bother with any further adjustments.
