Assos LL.607 S5 FI Mille Bib Tight

It’s Magic! The new Mile S5 generation of the Assos long legged bib tights for cold climatic riding conditions.

ALS Climarange: Ideally suited for early Winter

ALS Tips (Assos Layering System) Should temperature drop more than usual, wear a knee-warmer or leg-warmer underneath. Amazing, try it works! Upper body combined your LL.607 ideally with the new iJ.ha.Bu5. Brother and sister.

Engineering: The “big” news regarding engineering is the fact that all of the new Assos Mile S5 knickers and tights are based on the T.607. Meaning it has the construction skeleton of the Assos short which is more anatomical than the AEPD of the outgoing tights. In essence, the LL.607 is the long-legged version of the T.607, and that is good news from news from a performance point of view.

LL.607 is part of the new generation Campionissimo line. New pattern design, newly developed textiles, improved ingredients, a refined assembly process.

The LL.607 is built out of 12 panels, using 5 different textiles 29 components carefully engineered, defined and applied. Assos never compromises, and epically not on shorts tights. The main textiles used is an “improved” because we made slightly more robust in combination with the brand new RXQ fabric featuring 3D AirChannel inner texture. Not only did we redefine the fabrics, we also redefined a new 4 panel cut perfectly calibrated to textiles used. The “heart” of the LL.607 is its insert: The Assos S5 elastic interface as seen on the FI.Mille. Total comfort and high performance attitude is achieved by the total result of its construction and not because of a single application. Assos know how and expertise. Touch, ride, believe.

Magic, better performing

The main textile used are part of the Assos winter RX Series. Brand new is the RXQ fabric featured on the side panel. A development based on the legendary Assos RX textile. RXQ is the Assos actively breathable, low volume, 4 way stretch, soft touch, micro fiber insulator fabric engineered for cooler conditions. Uniquely, its brushed fleece inner surface is a hollow fiber micro polyester blend featuring 3D air channel structure, which creates a next-to-body micro air cushion. Trapped air is the best insulator and covering our body with such a structured textile enhances and promotes this function. Lowering the volume of the fabric while enhancing its push-pull performance optimizes moisture wicking and drying for best body heat retention properties. In addition, its surface construction enhances circulation. The original Assos RXQ-Pretty amazing!

AEPD: Tailored to fit the body in the cycling position. Created to “click on” to your body in the tuck position. Follows your movement without restriction. The “especially tricky” part of long legged cycling performance tights is the ‘kneezone’ . The Assos answer is the result of thousands of miles in the saddle combined with leading edge AEPD expertise. The result is good. Actually, very good. Minimized wrinkles, hence less friction and no seams behind the knee inside the “rotation” area. First introduced on the RX.LL 7 years ago, now perfected on the LL.607. Assos-often imitated, never equalled.

Tailored for total comfort during longer rides, T FI.Mille_S5 is the perfect long-distance bibshort. Thanks to its full ergonomic pattern design and four-panel construction, T FI.Mille_S5 guarantees optimal muscle compression, coupled with freedom of movement. The FI.Mille_S5 insert is slightly larger and thicker than the FI.13_S5. With more controlled elasticity and a built-in stabilizer, the FI.Mille_S5 insert gives even more comfort during your ride.

Assos cycling shorts are created following an organic approach. They are designed to "merge" with your body when on the bike.

S5 – The Evolution
The previous generation of ASSOS shorts were on the market for 7 years, the models virtually unchanged. This is not normal and practically unheard of within our industry, where superficial changes and "nonsense innovations" are presented yearly in order to create hype and to push sales.

At ASSOS, we do not believe in releasing a new product, unless there is an honest, valid improvement over the existing one.

If ASSOS, usually after many years, decides to discontinue a product and release its successor, there are always valid reasons: our product engineers have developed, and applied, new technologies to further improve your comfort and performance.
