Pas Normal Studios
The Pas Normal Studios Women's PAS Mechanism Pro Bibs are race-focused cycling bib shorts developed for high-intensity road riding and racing. Built around the Mechanism Pro platform, they combine structurally mapped fabrics with variable 4D-stretch to create targeted support, compression and a close second-skin feel at race pace.
The soft, silk-like stretch-woven main fabric provides a high strength-to-weight ratio while remaining abrasion-resistant and highly breathable. Variable stretch zones are integrated directly into the fabric to support the muscles and create a precise body wrap, while exposed elastane yarn at the leg openings functions as a silicone-free gripper to keep the bibs securely positioned.
A four-layer ultralight foam chamois is positioned specifically for comfort in an aggressive, speed-focused riding position. Quick-drying antimicrobial membranes help manage moisture and reduce friction during longer efforts, while lightweight bib straps and a breathable rear mesh panel maintain stability without unnecessary bulk. An integrated radio pocket provides discreet storage for a race radio or smaller essentials.
