Product Features

Variable 4D-stretch
The unique zones of stretch in the woven fabric give your muscles support and creates a second skin fit.

Radio Pocket
The back mesh features a pocket suited for a race radio or other smaller items that need to be stored during your ride.

Silicone-free Grippers
An exposed elastane thread woven into the leg part of the main fabric acts as a gripper, securing the Mechanism Pro Bibs in the optimal position.

Straps
Unique bib straps developed by Pas Normal Studios secure the Mechanism Pro Bib Shorts in an optimal position. The straps, developed in Italy, have a low level of elastic degradation even after a session of washing.
