Sidi Techno 3 Tensioner

The configuration depends on the specific model of your Sidi shoe and where the tensioner is located on the upper. Check your current tensioner's length or refer to your shoe's manual; generally, the long version is used for main closure straps, while the short version is for smaller adjustment zones.

These are specifically designed for Sidi shoes that utilize the Techno 3 closure system. If your shoes use a different closure mechanism, such as a ratcheting buckle or Velcro, these tensioners will not be compatible.

Replacing the Techno 3 tensioner is a straightforward process that typically requires only a small screwdriver. You simply unscrew the old unit from the shoe's mounting plate and secure the new one in its place.

The replacement tensioner typically comes as a standalone unit. You should retain the original screw from your current tensioner, as it is usually reused to secure the new component to the shoe.

No, these are replacement parts for shoes that already feature the Techno 3 system. They cannot be retrofitted onto older Sidi models that were designed for different closure types.
