Shorts/Bottoms

With the 160-gram Equipe RSR Bib Shorts S9, Assos started from scratch and re-engineered the platform as a whole—and came away with the lightest, most comfortable race-spec bib shorts to ever leave their laboratory. These bibs are made with Type 701kompressor material that delivers the perfect combination of compressive hold, durability, soft hand-feel, and the lowest weight possible. In other words, the material becomes your second skin, delivering phenomenal structural hold, breathability, and a silky smooth, uninterrupted wrap along the low back and thighs. Assos' new bracing system works together to stabilize the shorts and secure the insert in place. The S9 generation incorporates just two panels, with a primary “butterfly” panel fully wrapping the legs and converging in the rear to form the ergoBox structure. This design effectively frames the insert in place and provides you with an ultra-comfortable wrap that works in conjunction with Type 701 material for the best fit ever produced. The bib straps have also been redesigned using calibrated stretch throughout, with the rear section using a single section of elastic material—folded over on itself—forming an A-frame in the back. It delivers limited vertical stretch in order to add further stability. In the front, the straps are made of a more flexible material, with an antibacterial carbon weave, to lay flat and wick moisture. Assos also focused on a single insert platform, which allowed the freedom to reassess what is most crucial to a streamlined, race-spec insert. They reduced the overall footprint to shed additional weight, employed superAir microShock foam with 3D waffle, incorporated the kraterCooler system to increase airflow up front, and took additional measures to anchor the insert at the rear with a patented horizontal stabilizer. The result? Total ASSOS comfort you’ve come to know and trust, stabilized more than ever.

With six years of technology developments and our most advanced race insert to date, the Equipe RS Bib Shorts S9 forge new ground, bringing unmatched stability and comfort to your most demanding speed-focused applications. S9 marks the future of race-tuned comfort, built on an entirely new platform that’s been re-engineered from the ground up. We employed A-Lock Engineering, our new bracing system comprising proprietary textiles and technologies working together to stabilize the shorts and secure the insert in place. The S9 generation incorporates just two panels, with a primary “butterfly” panel fully wrapping the legs and converging in the rear to form our new ergoBox structure. This design effectively frames the insert in place and provides you with an ultra-comfortable wrap on your legs using our Type.441 textile, developed specifically for compressive hold and silky comfort. From here we added our unique rollBar, which uses the bib straps to stabilize the insert as your weight transfers from left to right while cornering. Each strap is sewn into the seam directly above the insert, ensuring it’s under pre-loaded tension at all times. The bib straps have also been redesigned using calibrated stretch throughout, with the rear section using a single section of elastic material—folded over on itself—forming an A-frame in the back. It delivers limited vertical stretch in order to add further stability. In the front, the straps are made of a more flexible material, with an antibacterial carbon weave, to wick moisture and lay flat. Key Features A-Lock Engineering: S9 racingFit system comprising new textiles and technologies working in harmony to stabilize the shorts and secure the insert in place. Butterfly Pattern: The primary textile panel fully wrapping the lower back and legs, coming together in the rear. Fewer seams leads to a more uniform hold, less weight, and greater comfort. Type.441: A patented 40-guage warp knit, developed specifically for compressive hold and silky comfort. 200g/m2, UPF 50+, moisture wicking (idroFil fastDry), iceColour, odorControl, and extremely durable. rollBar: A patented bracing design that uses the bib straps to stabilize the insert and lock it in place as your weight transfers from left to right while cornering. ergoBox: A square pattern construction that effectively frames the insert in the back, boxing it in for added stability. Carbon Xbib: A single section of elastic material—folded over on itself—forming a supportive A-frame that delivers limited vertical stretch in the rear. Above the “X” junction, a more flexible material is employed, incorporating an antibacterial carbon weave, to wick moisture and lay flat in the front. zeroWaist: A raw-cut, tape-reinforced edge for the smoothest transition possible between the body and fabric panel. More comfort with less pressure. Ultralight Leg Grippers: A light silicon treatment woven into the leg bands, which reduces fabric bulk and secures the shorts in place without any excessive pressure. 30% Seam Reduction: Flatter seams throughout, with fewer overall, translates to more comfort and lower overall weight (180g). mod.Dep S9 Basalt: Antibacterial microfiber booster top sheet in 3D basalt colourway. Pays homage to the lava stone that gives us strength, stability, and courage. superAir microShock foam: A lightweight open cell foam with a shock absorbing composition that returns to its original position, filling the gap every time pedaling position is changed in the saddle through the shift of weight. 3D waffle: A patented, three-layer perforated foam that increases breathability and eliminates excess weight. Surface Reduction Design: Insert footprint reduced from previous Equipe Evo pattern to shed extra grams. goldenGate: A patented technology that interrupts the stitching along both of the insert’s side panels, allowing a more three-dimensional freedom of movement in this sensitive, rotational area. Horizontal Stabilizer: a patented central stitch that secures the rear of the insert to the outer textile, eliminating shifting while pedaling out of the saddle. kraterCooler: System of small holes in the front of the insert that increases airflow so that your sensitive areas are kept cooler.
