Comfort that lasts all day long.

Multi-layer 3D chamois with Ortholite memory foam under ischial and perineum areas increases shock absorption by 20% compared to standard inserts.
Chamois has multiple levels of foam density, optimized to the weight of the cyclist.
Ergonomic and flatlock seams, mapped to the contours of the body, reduce irritation.
External elastic gripper with silicone for maximum grip and elasticity.

Muscle support to help you ride longer.

Lighter supportive and durable fabric provides solid muscle support.
Open mesh bib for better ventilation.

Memory foam for long-lasting comfort.

Ortholite memory foam returns to its original form as soon as pressure is released. So every time your pedaling position is changed in the saddle through a shift of weight, the foam fills the gap.

Anyone who has pushed the extremes of endurance riding knows that a high-performance bib short can make or break the experience. This short is designed specifically for long-lasting support and comfort. The Ergo 3D Pro Endurance chamois is made with dual-density Ortholite memory foam, giving them a super-plush feel on long-distance rides. Protecting the ischial and perineum areas and strategically shaped for the riding position, it improves shock absorption by 20% compared to standard inserts. Beyond the incredible chamois comfort, the Ksyrium Pro Bib Short also features a special fabric that adds muscle support. And the contoured shape of the short, along with ergonomic flatlock seams, helps prevent any chafing. Lastly, the leg openings are made with a wide elastic material and silicone inner treatment that comfortably grips your legs. It’s not every day that you push well beyond 100km and spend long hours in the saddle. But it’s nice to know that when you do, your bib short is up for the effort.
