Engineering: The “big” news regarding engineering is the fact that all of the new Assos S5 knickers and tights are based on the T.607. They have the construction structure of the Assos T bibshort, which is more anatomical then the AEPD of the outgoing knicker. In essence, the TK.434 is the knickered Spandex version of the T.607, which is great news for performance: improved anatomical cut, improved compression fit. TK.434 is part of the next generation Campionissimo line, which features new pattern design, newly developed textiles, improved ingredients, a refined assembly process and available only with the Mille_S5 insert.
Assos TK.434 is built from 13 panels, using 4 different textiles 7 components all carefully defined, engineered and applied. Your TK.434 is assembled by hand, undergoing 34 assembly steps by 4 different human operators and made in our own Assos assembly plant in Europe. Leading up to production, the Assos Centro Studio, Switzerland (our research center in Ticino) spent 3 years researching, making, testing, improving (and destroying) a total of 47 concept and road prototypes. Assos never compromises. We are especially committed to creating the best shorts, knickers and tights. The main textile used in the TK434 is the Type A.434 Assos compression spandex, which is used in all Assos shorts. Total comfort and high performance attitude are achieved by integration of construction, pattern and materials. Assos know-how and expertise. Touch, Ride, Believe.
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 “difficult to engineer ” part of cycling knickers is the knee zone. The Assos solution is the result of thousands of kilometres in the saddle combined with leading edge AEPD expertise. With the introduction of the S5 knickers, we are introducing, our next generation knicker-specific result, and we are delighted with the result: minimized wrinkles and less pressure on the knee by featuring a seamless “rotation” area behind the knee. Another new feature is the incorporation of a warm, fleecy Assos RXQ fabric panel over the knee cap, to protect your precious knees by keeping them insulated in cooler riding conditions. Attention to detail! Others try, Assos achieves.
MILLE_S5 - The long distance comfort short Tailored for total comfort during longer rides, MILLE_S5 features full ergonomic pattern design, providing muscle-compression with total freedom of movement, thanks to its 4-panel construction. Ideally suited to more robust riders who prefer a "less tight" feeling.
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. Assos cycling shorts are created following an organic approach. They are designed to "merge" with your body when on the bike.
