The ASSOS EQUIPE RSR Bib Shorts S11 are the most advanced race bib shorts in the ASSOS range, engineered for elite-level racing and high-intensity performance. Developed on the latest S11 platform, these ASSOS racing bib shorts combine ultra-compressive textiles, aerodynamic construction, and WorldTour-tested stability for riders who demand maximum efficiency at speed. Designed for warm conditions and aggressive riding positions, the EQUIPE RSR S11 delivers a true second-skin feel with exceptional breathability and muscle support.
ASSOS integrates Kompressor textile across the legs to wrap the muscles in firm compression, helping reduce fatigue caused by road vibrations during long, high-power efforts. The seat and core use the softer Type.911 fabric to relieve pressure and improve airflow, ensuring long-distance comfort without sacrificing durability. The RSR S11 insert is optimized for racing positions and combines low-volume cushioning with advanced ventilation and targeted shock absorption for sustained performance in demanding race environments.

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 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.
