Pas Normal Studios Mechanism Pro Bib Shorts Advanced fabrics meet impeccable detail in the Pas Normal Studios Mechanism Pro Bib Short. Designed to deliver pro-level performance, the short uses a race fit optimised for the riding position, and structurally mapped fabric with zones of variable 4D stretch create a second-skin fit and provides support to the muscles. The soft, silky feel maximises comfort and abrasion resistance is high, preventing excess wear.  The four-layer chamois is another highlight, using strategically placed padding to cushion and protect the rider's most sensitive areas to provide long-ride comfort. Silicone-free grippers are woven into the lower portion of the leg and create a smooth transition from material to skin while preventing the short from riding up while pedalling. A radio pocket integrated into the rear mesh makes a handy extra detail come race day.
