Assos Equipe RS Bib Shorts S9

The definitive bib shorts for competitive, committed cyclists from the company that originally defined the racing shorts genre—and continues to lead in driving it forward.

It’s only fitting that the latest generation of ASSOS inserts—the most advanced available from any manufacturer—is partnered with bib shorts completely re-engineered, with no design choice taken for granted or left unquestioned. The resulting bib shorts are atypically advanced—which makes them typically ASSOS. The shorts combine textiles and technology in an interwoven network of wrapping compression, silky comfort, and tensile pre-load to keep everything from the leg panels to the insert securely in place. It’s taken six years of in-house development and testing by WorldTour riders, but the EQUIPE RS S9 Bib Shorts are the definitive statement in cycling shorts from the cycling shorts company.

The finer details

FEATURED FABRICS
Type.441 is a gently compressive, silky smooth material that feels more abrasion-resistant than your typical bib short material because it is. It also actively cools while protecting against UV rays and resisting odor.

CONSTRUCTION/FIT
A-Lock Engineering is our S9 racingFit realized for bib shorts. Every fabric panel, strap, and stitch is engineered for stability and confident comfort. ASSOS shorts are legendary; this fit design is why.

ENGINEERING
Butterfly Pattern: The main textile panel wraps the lower back and legs, reducing seams and providing a more uniform compression across the shorts’ body.
Carbon Xbib: An A-frame bib that limits vertical stretch in the rear, ensuring a confident fit and stabilizing the chamois and main body panel.
Ultralight Leg Grippers: The leg bands feature a silicone treatment woven through the bands themselves, creating a secure hold without restriction or lumpy transitional ridges.

INSERT
EQUIPE RS Insert: Antibacterial microfiber booster top sheet in 3D basalt colorway. Pays homage to the lava stone that gives us strength, stability, and courage.
goldenGate: A stitching pattern that anchors the front and back but lets the insert’s body float, allowing the insert to move with your body rather than against it.
superAir microShock foam: A light, shock-absorbing foam that springs back to its original shape, filling the gaps that open and close between body and insert during the pedal stroke.
kraterCooler: Perforations in the insert’s leading edge that draw air across the insert to maintain cooling breathability on hot summer days.
