Deda Elementi Launches Wheelset Range

From Deda:

Deda Elementi is a point of view... a state of mind. Deda Elementi produces our bicycle components with care and passion. We are very serious about our components, and we put all our engineering and design experience and passion for cycling into them, as we have with components that champions like Lance Armstrong, Jan Ulrich and Paolo Bettini have ridden to glory.

When Deda Elementi decided to create a wheel range, we stayed true to our core traditions of technical innovation and classic Italian design sensibility.

DEDA ELEMENTI Wheels: Key Engineering & Design Features:

Reverse Inertia Design

To make our new wheels faster, Deda Elementi used the principle of Reverse Inertia. The moment of inertia of an object about a given axis describes how difficult it is to change the objects angular motion about that axis. That physics lesson was key in the development of Deda Elementi Wheels.

The further out the wheel's mass is, the more rotational inertia the object has, and the more rotational force (torque, the force multiplied by its distance from the axis of rotation) is required to change its rotation rate. We made a faster wheel with a light, strong rim by moving the spoke nipples to the hub. Simple and effective.


Special Formula Resin For High Temperatures


Deda Elementi uses the latest carbon composite technology to refine the polymer mix in our new carbon composite rim. We combined 3K and UD carbon for the structure of the Deda with extreme heat-resistant aerospace polymer resin to withstand high temperatures under extreme braking force. We then performed extensive road and lab testing; Deda Elementi wheels were tested by applying brake force of 120kg for 30". The basalt fiber brake track reached almost 200 °C, but our Deda Elementi clincher & tubular rims didn't fail.



The Perfect Pull

Deda Elementi designed our wheels to have a perfect spoke pull. We created a specially designed internal washer, positioned just under the spoke head, then mated to a special internal rim profile to allow the spoke to seat accurately and thus attain perfect alignment. Our simple and elegant solution makes the spoke life longer and the Deda Elementi wheels more reliable, as the spoke always pulls in its ideal position. Each spoke is tensioned at 120kg and our perfect spoke pull aligns the tension with the spoke axis.



Augmented Brake Track & Big Pad

After considerable research, Deda Elementi clincher wheels have two key technical features for enhanced stopping efficiency: Augmented Brake Track (ABT) & Big Pad. Deda Elementi has increased the width of the brake track to 15mm and added a larger special compound brake pad, called Big Pad, which in combination add enhanced stopping efficiency to Deda Elementi clincher wheels.

All Deda Elementi wheels include:

SPARE PARTS: 2x rim tape, 4x special compound brake shoes, 2x front spoke black, 2x rear spoke, drive side, black; 2x rear spoke, non drive side, black.

Deda Elementi: Superleggero Stem & Superleggera Handlebars

All new for 2013 from Deda Elementi are the Superleggero stem, Superleggera 31.7 mm diameter and Superleggera 35 mm diameter handlebars.

Superleggero Stem:
Deda Elementi's all-new Superleggero Stem is the result of their search for the ultimate functional shape, stripped of any excess. Made in 7050 3D forged aluminum alloy and using Ti screw fitments. Deda claims that it is the lightest production stem available; 99 grams at 110 mm length (80-90-100-120-130-140 mm, all in 31.7 clamp size). Available in Black Anodized and Black on Black.

Superleggera Handlebars:
Superleggera handlebars use a "revolutionary" new type of carbon fiber that allows Deda to shave every excess gram of weight. HR40 Tonne carbon fiber and a proprietary new hi-strength nanotechnology resin with a unidirectional carbon layup create a compact composite material that allows Deda to achieve a weight of 180 grams for a 42 cm (measured outside to outside). These handlebars will be available in 42 - 44 - 46 cm for 31.7. Finish in Carbon UD, Black on Black.

Deda's "35" handlebars (see Andre Greipel's setup here) will also be available in a Superleggera version. Same weight, sizes and finish available as the 31.7 handlebars.

Deda Elementi Joins the Monolink Revolution

All new from Deda Elementi for 2013 is the Mnlink Seatpost, a full carbon fiber monocoque seat post for the new seat rail standard launched by Selle Italia in 2009.

Deda Elementi 's Mnlink Seatpost allows separate adjustment of the set-back and the saddle inclination, an advantage for the rider who is seeking more adjustability and easier-to-adjust seatpost.

Deda Elementi Mnlink seatpost specifications:

Diameter: 31,6 mm and 27,2 mm
Length: 350 mm
Weight: 188 grams
Finish: carbon UD

Deda Elementi 35 for the "Gorilla" Greipel

Andre Greipel is using Deda Elementi's TRENTACINQUE (35) combination of stem and handlebar at the Tour de France. The powerful German, nicknamed the "Gorilla", can generate more than 1300 watts in a sprint so a stiff handlebar and stem combination is of utmost importance.

Deda Elementi, part of the Deda Group which includes Dedacciai, says that their 35mm handlebar shows a 50% greater stiffness than a normal 31.7 mm handlebar. "Subjecting a normal 31.7 mm diameter handlebar and a handlebar with a 35 mm diameter to the same load (300N applied at the outsides of the drops) imagining them centrally clamped to their own stems, we get a maximum deflection of the 31.7 mm diameter handlebar of 3.318 mm, compared with a recorded maximum deflection of the 35 mm diameter handlebar of 1.609 mm. A difference of 1.709 mm corresponding to a 51.5% increase in stiffness. The data collected are the result of FEM tests."

Through the years the size of handlebars for racing bikes has continued to grow in search of greater stiffness:
25.4 ISO standard)
26.0 Italian standard
26.4 Cinelli standard
27.0 Titan
31.8 current standard for carbon handlebars
35.0 Deda

Standards? Only Stiffness Counts: Deda 35

Things are getting messy with several manufacturers creating their very own proprietary designs for various bike components. Some will survive and become standards, and others will leave us years down the road trying to find replacement parts.

Deda Elementi, with it's introduction of "Trentacinque" (35) at Eurobike, upped the stiffness ante from the 31.8 mm stem and handlebar interface standard to 35 mm.

The handlebar has a 35mm, round, diameter and weighs 210 grams and is available in widths of 42-44-46 cm. The stem has a weight of 136 grams and is available in lengths of 90, 100, 110, 120, and 130mm. Colors: red, white, carbon.
