The ultimate climbing bike


“We build Ourea to allow you to ascend mountains with ease and pleasure.

It is the pure racing bike that climbers want and need: light, stiff, and fast.”


The ultimate tool for conquering hills – the DIZO Ourea, the size S frame weighs 775g. Weighing in at a fraction of the weight of traditional road bikes, this revolutionary new design is the key to achieving your best climb times yet. Our deep expertise in composite has harnessed the power of carbon fiber to create a bike that is not only incredibly lightweight, but also unbelievably fast and responsive. With the DIZO Ourea, you’ll be able to navigate even the trickiest switchbacks with ease, while its superior power transfer ensures maximum efficiency on the steepest ascent and in the races.


Our expertise in carbon technology allows us to create exceptional carbon bikes for the peloton. Our approach starts with careful material selection and optimization to ensure that each component of the frame is utilized to its full potential. By strategically incorporating different types of carbon in critical areas, we achieve optimal weight reduction, stability, and strength. The deepest layer of the Ourea is reinforced with Toray T1100G, a highest grade of carbon fiber in the market that greatly enhance strength and stability while minimizing weight. M40, M46 and ultra-high modulus carbon composite are also used in the frame for tuning the stiffness within a specific areas, making it highly exceptional stiff and lightweight.


The DIZO Ourea shows the high technical proficiency can incorporate with the minimalist aesthetics of the frame. Hidden Cable Routing (HCR) technology plays a crucial role in integrating the cables into the Aero-compact Stem, resulting in clean appearance and improved aerodynamic performance. To remain the aesthetics beauty of the frame and retain the aero benefits, axle-thru nut is also completely integrated into the frame and fork.


Frame weight (S size build-ready) – 775 gram

Fork weight (uncut) – 330 gram

Our advanced manufacturing solution has evolved to offer the ultimate performance by utilizing dual mold forming technology that combines high-pressure and heat to eliminate any excess resin from the base material, making the inner wall of frame super smooth and flat. This process significantly enhances the strength, lightness, and efficiency of the carbon. The Ourea’s impressive stiffness-to-weight ratio plays a vital role in its exceptional performance, ensuring that the bike remains lightweight while maintaining ride stiffness, durability, and responsive handling.

Countless repetitions and hours dedicated to refining the design, every aspect of Ourea’s fork is dedicated to achieving the ultimate objectives of enhanced control, stiffness, and comfort.

In order to enhance lateral stiffness in the rear triangle, while simultaneously ensuring slender seat stays for improved compliance and comfort.

As a pure racing bike, the Ourea is UCI approved that ensuring you to be able to participate in every race safely.

With meticulous attention to detail, the BB junction has been thoughtfully designed to facilitate direct power transfer, ensure the high torsional stiffness, and serves as the pulsating core of the Ourea.

Split spacers enables riders to easily adjust the height of the cockpit according to their specific fit requirements, all without the need to undo any cables.

The Ourea’s total aero integration does not only provide the cockpit integration design, the front and rear axle-thru nuts are also integrated into the frame and fork.

The integration of axle-thru design showcases the harmonious coexistence of exceptional technical proficiency and beautiful minimalist aesthetics.
