The ASSOS EQUIPE RSR Bolide Bib Shorts S11 are the most aerodynamic race bib shorts ever developed by ASSOS, engineered specifically for time trials, track racing, and the fastest road race environments. Built on the advanced S11 racing platform, these elite ASSOS racing bib shorts combine extreme compression, aerodynamic textile engineering, and WorldTour-proven stability to deliver maximum speed and efficiency. The Bolide concept focuses on minimizing drag while maintaining the muscle support and comfort required for sustained high-power efforts.
ASSOS uses advanced compressive textiles to stabilize the major muscle groups and reduce fatigue caused by road vibration during maximal efforts. The aerodynamic panel construction is optimized for aggressive race positions, ensuring the shorts remain perfectly aligned when riding in an aero tuck. The RSR S11 insert is engineered for competition, combining low-volume cushioning with advanced ventilation and shock absorption to deliver comfort without sacrificing speed.

The PNS Women’s Mechanism Logo Bibs are optimised for high-intensity training rides and races. Built around the familiar Mechanism platform, they combine a close, performance-led fit with the clean, understated look of the logo edition, making them a strong option for fast training, long days in the saddle, and harder race efforts.
The construction focuses on stability, breathability, and long-ride comfort. Elastic grippers help keep the bibs securely in place, perforated mesh straps and a front mesh panel add ventilation, and the chamois uses a multi-layer foam construction with an antimicrobial surface for comfort and moisture management. Chamois stitching is also designed to reduce friction and improve durability.

The Women’s PAS Mechanism Pro Bibs are optimised for high-intensity training rides and races. As part of the PAS collection, they are built on the same performance-led platform as Mechanism Pro, combining a tight, aerodynamic fit with a women’s-specific construction tuned for speed, support, and long hours at race pace.
The bibs use a variable 4D-stretch construction to create a close, stable fit on the bike, while silicone-free grippers keep the leg opening secure without unnecessary bulk. A 4-layer ultralight chamois is designed for high-output riding, and the addition of a radio pocket underlines the bibs’ race-focused intent. The overall result is a women’s cycling bib short that feels streamlined, technical, and purpose-built for harder efforts.
