EQUIPE RSR T SuperlegerS9

Assos EQUIPE RSR T Superleger S9

The Assos EQUIPE RSR T Superleger S9 is one of the lightest and most ventilated racing bib shorts in the Assos range, designed for maximum intensity in hot conditions – both outdoors and on indoor trainers. At just around 120g, it builds on the S9 platform and combines ultralight textiles with noticeable stability, ensuring the chamois stays reliably in place even at high speeds. The main panel uses the airy Breezer Tex, while the saddle contact areas feature the particularly soft and durable OSSIDIA material for support. The result is noticeably reduced friction potential, fast drying, and a cooler feel during long intervals or hot summer rides in Switzerland.

• Approx. 120g total weight for minimal inertia and fast drying.
• Main panel in Breezer Tex for maximum breathability and soft feel.
• Contact zones in OSSIDIA for robust support and targeted compression.
• A-Lock Engineering with rollBar straps, ergoBox and Butterfly panel for chamois stability.
• RS SUPERLÉGER insert with superAir microShock foam and 3D waffle for low weight and ventilation.
• goldenGate and whirlKrater for more freedom of movement and air circulation in the chamois.
• zeroWaist finish and ultraLight Leg Grippers for pressure-free fit at waist and legs.
• Material mix: 64% Polyamide / 27% Elastane / 9% Polyester.

Technical Details and Features

Assos's S9 modular system anchors stability through A-Lock Engineering, preventing weight shifts in the saddle from displacing the chamois. The rearward-routed rollBar straps work together with the ergoBox construction and surrounding Butterfly panel, cleanly distributing forces and reducing friction. The airy Breezer Tex brings mesh-like ventilation to the leg areas, while OSSIDIA provides targeted support and abrasion resistance front and rear. In use, the RS SUPERLÉGER chamois reduces moisture absorption; the superAir microShock foam layer, perforated 3D waffle, and seamlessly integrated goldenGate layout promote cushioning, breathability, and freedom of movement. Strategically placed whirlKrater perforations increase air exchange, while zeroWaist and ultraLight Leg Grippers provide a smooth transition without pressure edges. The interplay of these components creates a light yet clearly supportive race fit for high power output in training and competition.

Applications and Benefits

These bib shorts feel most at home in very warm conditions, during high-intensity intervals, and indoor sessions at home – such as on smart trainers. Thanks to their open, fast-drying textiles, they're equally suited to hot climbs on the road bike in Switzerland, when the air is thin and sun exposure is high. The stable chamois layer also supports out-of-saddle efforts and frequent position changes, such as in criteriums or short hill races. At the same time, the look remains "classic" and not perforated, so you can ride them outdoors even on the hottest days without issue. Cycling media also rate the Superleger S9 as particularly suitable for indoor training with a focus on breathability and comfort.

Fit, Materials and Service

The EQUIPE RSR T Superleger S9 is designed around the raceFit characteristics of the S9 family and fits accordingly compressive and close to the body; for optimal performance, it should fit snugly in racing position. It's available in blackSeries colorway and in sizes from XS to 2XL, covering a broad spectrum of ambitious riders. The material mix of 64% Polyamide, 27% Elastane and 9% Polyester ensures fast drying, stability, and a smooth feel on the skin. Assos backs the product with 2 years warranty and a Crash Policy, providing additional security for regularly training riders. Those who frequently train indoors also benefit from the reduced water absorption of the straps and materials – keeping the shorts noticeably lighter even during long Zwift races or interval blocks.
