Performance Wheels – More Complex Than Expected?
Competitive cycling, whether on smooth asphalt or rough gravel, is the ultimate synergy between rider and technology, placing the highest demands on both rider and equipment. The wheels, in particular, are more than just the link between the bike and the road: they are the functional heart of every ride, combining performance, safety, and riding enjoyment. In our series “Leeze Wheels 1x1,” we dive deep into the world of performance wheels and explore why wheels are more than just carbon rims.
The Core Requirements: What a Performance Wheel Really Needs to Deliver
A performance wheel is more than the sum of its parts; it is a complex interplay of precision, engineering expertise, and extensive development know-how. At Leeze, we have identified four essential core requirements that a competitive performance wheel must meet:
Aerodynamics:Fast wheels are aerodynamically optimized wheels. With carefully designed rim profiles that drastically reduce air resistance, we maximize speed.
Stiffness: High wheel stiffness is essential for optimizing power transfer and ensuring a dynamic, responsive ride.
Durability: Our wheels are built to withstand the rigors of racing and are designed to perform reliably in any situation—even on the fastest descents and the roughest terrain.
Lightweight: Reducing overall weight is crucial for quick acceleration and efficient climbing. Every gram counts.
Application scenarios and their requirements
Depending on the application scenario, we assign different levels of priority to the four core requirements. The following five scenarios clearly illustrate which of the basic requirements take precedence when developing a suitable wheel:
Time trials and triathlons: In these disciplines, where every second counts, we rely on extremely aerodynamic wheels—high-profile rims over 70 mm and disc wheels with uncompromising aerodynamics. Agility and weight are optimized, though they are not the primary focus of development. Our CC78 Disc EVO WASO delivers maximum performance in these events.
Bergiges Terrain: Bei Anstiegen zählt jedes Gramm. Unsere Laufräder mit niedrigen Felgenprofilen (<30mm) kombinieren Leichtigkeit mit Torsionssteifigkeit. Trotzdem sind wir uns bewusst, dass auch auf diesem Terrain die Aerodynamik eine wichtige Rolle spielt. Der CC25 Allroad EVO WSTO setzt hier mit nur 1240 Gramm neue Gewichts-Maßstäbe.
Flat routes with little elevation: Here, aerodynamics are the top priority. Aerodynamic rim profiles with rim heights of 50–60 mm are preferred to optimize airflow around the wheel. At the same time, carbon wheels retain their agility and lightness. This is where our bestsellers, the CC50 Disc BASICand the CC58 Disc EVO WASO, shine.
All-road and Gran Fondos: For these versatile events, our wheels offer a balanced combination of weight, aerodynamics, and comfort. At the same time, we prioritize maximum durability so you can tackle even long Gran Fondos on varied terrain with confidence. The CH40 Allroad BASICis the optimal choice here on any terrain.
The Complexity Behind Performance Wheels
The development and optimization of performance wheels is a complex process that requires specialized knowledge and precision.This makes wheels extremely complex to develop and optimize, and more costly compared to other components on a road bike. There are four key cost drivers in the development, optimization, and manufacturing of our wheels that we would like to outline transparently:
Manufacturing Process: Our manufacturing techniques are precise and complex to meet high standards of quality and performance. We allow virtually no room for manufacturing tolerances in our wheels to reliably deliver maximum performance. Rennrad-Magazin has already taken a look behind the scenes of our development and manufacturing processes.
Testing procedures: Every Leeze wheel undergoes rigorous testing to guarantee its performance and durability. At the same time, we promise optimal service and a lifetime crash replacement warranty for all Leeze wheels purchased from us.
It’s clear: Investing in a Leeze Performance wheel is an investment in the highest quality, performance, and service—and in an exceptional riding experience.
Now that we’ve highlighted the demanding—and in some cases very diverse—requirements that our performance wheels must meet, let’s take a closer look at the wheel itself in Part 2/3: Wheel Components and Accessories. We’ll show you the key components that make up performance wheels and the additional parts needed to turn a wheel into a fully functional wheel system.
