Assos Equipe RS Spring/Fall Bib Tights S11

The Assos Equipe RS Spring/Fall Bib Tights S11 sit at the top of Assos's racing lineup for cool, dry conditions, built for riders who keep the intensity up once the temperature drops into the 50s and 60s. These bib tights use OSMOS Light, the lightest insulation in Assos's OSMOS thermal fabric family, across the main body. The warp-knit construction actively regulates temperature while adding compressive support, so the tights don't just trap heat — they help manage it as your effort changes over a ride. A lightweight SPHERE Ultra softshell panel covers the crotch and lower legs, shielding you from wind and road spray without turning the tights into a sauna, which is the balance Assos was chasing when it updated this generation of the S11 tights.

Fit follows Assos's AEPD 11 racingFit, a second-skin aero silhouette developed with feedback from WorldTour riders and built around 360-degree compression and stability. The Louvre Tec knee pattern shapes the fabric around the joint specifically to cut down on friction through thousands of pedal strokes, and a Soft Compression Module at the waist keeps the tights snug without digging in when you're in an aggressive, low position. The bib straps use Assos's Soft X-Frame construction — an A-frame suspension that limits sag on the lower back and keeps the chamois and main panel stable during hard efforts — anchored across the shoulders with the lightest straps in the range. At the ankle, a raw-cut, hemless cuff sits flush under rain or wind booties instead of bunching, and reflective details on the lower legs add visibility during low-light rides.

The EQUIPE RS S11 chamois insert uses a single-layer, 9mm Shock-Absorb Damping System that's thermoformed to eliminate pressure ridges, built on the same 3D Waffle perforated foam and free-floating design as Assos's SCHTRADIVARI summer shorts. Here, that insert sits behind the windproof softshell panel, so you get the breathability of a summer-weight chamois with the wind protection a cooler ride demands. Perforation patterns called kraterCooler and whirlKrater route airflow across the insert from multiple directions rather than a single channel, which keeps things dry without cold air cutting straight through. It's worth knowing these tights are built for dry conditions specifically — wind and water resistance are limited to the softshell panel, not the whole garment, so they're best paired with a rain jacket if the forecast turns wet. For cool, dry rides, Assos recommends layering them with the EQUIPE R Spring Fall Jersey or Gilet.
