Assos EQUIPE RS Bib Shorts S9 - blackSeries

#FASTGETSFASTER - The all-new Assos S9 Collection

Where could Assos go from S7? This question unfolded on the road, at their textile lab, and in the toughest races on the planet over the past six years. S9 marks the future of race-tuned comfort, built on an entirely new platform that’s been re-engineered from the ground up. With years of testing and feedback from riders at the highest level of the sport, Assos continue to see the most advanced insert technology being only as good as the framework that supports it.

Details of the Assos Equipe RS Bib Shorts S9

Consider the hard cornering, in-to-out-of-saddle pedaling, and hours of body repositioning that greatly impact your shorts and the way its insert functions, and ultimately the comfort both are able to provide. To address these points, Assos employed A-Lock Engineering, their new bracing system comprising proprietary textiles and technologies working together to stabilize the shorts and secure the insert in place.

Stability and Comfort

The S9 generation incorporates just two panels, with a primary “butterfly” panel fully wrapping the legs and converging in the rear to form the new ergoBox structure. This design effectively frames the insert in place and provides you with an ultra-comfortable wrap on your legs using Type.441 textile, developed specifically for compressive hold and silky comfort. From here Assos added the unique rollBar, which mimics a race car’s anti-sway bar by using 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.

Equipe RS Insert - S9 Seat Pad

For the insert, Assos focused on a single race-mission platform - evolved from the proven Equipe Evo - giving Assos the freedom to reassess what is most crucial to a streamlined, race-spec insert. Assos reduced the overall footprint to further shed 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 the patented horizontal stabilizer. The result? Total Assos comfort you’ve come to know and trust, stabilized more than ever.

Technologies of the Assos Equipe RS Bib Shorts S9

A-Lock Engineering: In the harshest racing environments, your shorts’ insert is only as good as the materials and patterning that support it. A-Lock Engineering is that framework. It’s the system of textiles and bracing technologies that stabilizes the shorts and secures everything in place.

rollBar: The patented bib-strap bracing design secures the insert, ensuring it stays firmly planted while corning or pedaling out of the saddle.

Type.441 Material: A patented 40-gauge warp knit, developed specifically for compressive hold and silky comfort. 200g/m2, UPF 50+, moisture wicking (idroFil fastDry), iceColor, odorControl, and extremely durable.

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 with tuned vertical elasticity.

Butterfly Pattern: Single fabric panel on the lower back and legs delivers consistent, uniform hold and yields a lower overall weight.

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: New Lycra/elastane leg band structure naturally grips the thigh - free of silicon treatment - to deliver a smooth, ultralight hold.

Technologies of the Assos Equipe RS - S9 cushion

S9 Basalt: Antibacterial microfiber booster top sheet in 3D basalt colorway. Pays homage to the lava stone that gives us strength, stability, and courage.

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.

Surface Reduction Design: Insert footprint reduced from previous Equipe Evo pattern to shed extra grams.

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.

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.
