Assos Equipe RS Spring Fall S9 Bib Short

The Assos Equipe RS Spring Fall S9 bib short is the ideal cycling legwear for the cooler spring and autumn days, when a long tight is still too warm but a summer short lets the cold wind get to you. That is the perfect time for this bib short! As the crotch is windproof, this vulnerable area remains well protected when there is a cold biting wind. The fabric of the short itself is also slightly thicker and provides more warmth than that of a regular short worn in summer. The side panels are made of Osmos Heavy material, a technical fabric that gives you two additional advantages. It is brushed, which not only feels extremely soft but also provides an extra insulating layer. And this fabric provides light compression for good muscle support during cycling so that you don't tire easily.

The seat pad used in this short is intended for the competitive cyclist. While the kraterCooler ventilation openings in the front have been left out, the pad does feature Assos' patented 'goldenGate technology', of course, which ensures the best possible fit and makes this chamois best suited to medium-distance cycling.

A-Lock Engineering
S9 racingFit system with new textiles and technologies that work together to stabilise the cycling short and keep the chamois in place.

Osmos Heavy
This warp-knit material is a very important textile which is also one of the heaviest in Assos' Osmos family, 290 g/m2. It features asymmetric stretch and a soft, durable construction. The high degree of insulation is due to the brushed surface on the inside.

Sphere Ultra
This is a patented 2L windproof, waterproof and extremely breathable softshell, made with a PU-bonded membrane for additional water repellency. The result is maximum insulation with minimum fabric.

RollBar
A patented principle that, thanks to the bib straps, keeps the seat pad perfectly in place as you shift your weight from right to left in the bends. This principle is similar to the function of the stabiliser bar in racing cars.

ErgoBox
This is a square pattern construction that frames the chamois at the back and encloses it to create additional stability.

Butterfly Pattern
This refers to the main textile panel that fully covers the lower back and legs. A reduced number of seams results in a more uniform compression, reduced weight and increased comfort.

Carbon Xbib
One-piece elastic material that is folded to form a supportive A-frame that limits vertical stretch at the back. Above the X-joint a more flexible material is used which contains antibacterial properties, manages moisture and remains flat at the front.

Ultralight Leg Grippers
The new lycra/elastane structure is woven into the straps and wraps the thighs. The result is soft, ultra-light compression. No silicone treatment is required.

EQUIPE RS Insert (no krater)
Competition worthy elastic chamois in 3D basalt colour. It does not feature the kraterCooler ventilation openings at the front.

SuperAir microShock foam
This is a lightweight open-cell foam with a shock absorbing composition. The foam returns to its original position and fills the gap each time the position in the saddle changes due to weight shift.

Assos Waffle/3D-Waffle
This is a patented three-layer perforated foam that increases breathability and eliminates excess weight.

Assos goldenGate
This is a patented technology that interrupts the stitching along both side panels of the chamois. This allows for more three-dimensional freedom of movement in this specific and sensitive area.

Horizontal Stabilizer
A patented central stitch that attaches the back of the chamois to the outer fabric to prevent the chamois moving when you step on the pedals.
