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: now available at Deda Elementi dealers

Deda Elementi / 45mm Rim Depth
There are 2 wheel models in the Deda Elementi wheel range with 45mm Depth:
WD45CCL clinchers & WD45CTU tubulars.



WD45CCL Clincher Wheelset: Use for high speed, maximum air penetration, extreme light weight and matchless style.

Reversed Inertia Concept design
45mm deep profile carbon fiber clincher rim, with UD and 3K high modulus carbon fiber combined structure, special heat-resistant resin with basalt fiber 15mm brake track
Sandvik T30218/10 stainless steel aero elliptical black spokes
Active Rotational Balance spoking: lighter spokes at valve stem offset wheel weight imbalance
6061 aluminum alloy compact body hub hub, double seal radial ball bearings, 18H front 20H rear, 6061 aluminum alloy axle 15 mm OD, 3 pawl freehub, for Shimano / SRAM / Campagnolo 11s
Wheelset Weight: 1460 grams (no QR)
Meets and exceeds EN 14781 test standards




WD45CTU Tubular Wheelset: Use for high speed, maximum air penetration, extreme light weight and matchless style.

Reversed Inertia Concept design
45mm deep profile carbon fiber tubular rim, with UD and 3K high modulus carbon fiber combined structure, special heat-resistance resin with wider, ABT basalt fiber brake track
Sandvik T30218/10 stainless steel aero elliptical black spokes
Active Rotational Balance spoking: lighter spokes at valve stem offset any wheel weight imbalance
6061 aluminum alloy compact body hub hub, double seal radial ball bearings, 18H front 20H rear, 6061 aluminum alloy axle 15 mm OD, 3 pawl freehub, for Shimano / SRAM / Campagnolo 11s

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:
