Assos' Lightest, Most Comfortable Race Spec Bib Shorts — Equipe RSR Bibshort S9

To create the highest performing racing bib shorts, Assos needed to rethink the platform as a whole, and strip away any component that didn't contribute to the primary objective of reaching that untapped level where speed and total comfort coalesce. Mission accomplished.

Meet the Equipe RSR Bib Shorts S9.

Advanced insert technology.

In the harshest racing environments, we see the most advanced insert technology being only as good as the framework that supports it. Consider the abuse a pair of shorts goes through during an average day at the office for a World Tour rider: aggressive cornering, abrupt transitions between road surfaces, constant in-to-out-of-saddle pedaling, and hours of body repositioning.

All of this greatly impacts the shorts composition and the way its insert functions, and ultimately the comfort both are able to provide.

Impressive Textiles.

To mitigate these effects, without tacking on weight, Assos' first point to address for the RSR project was the textile itself. The latest material, Type.701kompressor, delivers the perfect combination of compressive hold, durability, soft hand-feel, and the lowest weight possible. Type.701 becomes your second skin, delivering phenomenal structural hold, breathability, and a silky smooth, uninterrupted wrap along the low back and thighs.

Utilizing A-Lock Engineering and just two panels, the shorts provide stabilization and security for the chamois.

This design effectively frames the insert in place and provides you with an ultra-comfortable wrap that works in conjunction with Type.701 for the best fit from Assos yet.

Pro Fit.

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 a 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.

Evolved from the Equipe Evo, the race-ready insert is ultra streamlined, employing superAir microShock foam and the kraterCooler system to increase airflow and stabilization.

Put it all together and you're top-step ready with total ASSOS comfort you've come to know and trust.
