G3 - Campagnolo
If you're interested in racing bike wheels, you've probably already heard about Campagnolo's G3 shelving. This unique shelving is distinguished by its innovative arrangement of beams, which improves both rigidity, power transfer and driving comfort. But concretely, how does it work, and what benefits can it bring to your carbon wheels? That's what we're gonna see together.
What is Campagnolo's G3 technology?
The G3 shelving is based on an original pattern where the rays are grouped by three, instead of being evenly distributed around the rim as on a traditional wheel. These groups of three rays are organized according to a 2:1 ratio: the wheel has twice as many rays on one side as on the other. This design patented by Campagnolo is used on high-end wheels such as Bora WTO, Bora Ultra WTO, Shamal and several aluminum models of the brand.
Why this 2:1 provision?
The idea behind this design is to balance the tension exerted on the wheel at best. By increasing the number of spokes on the side most stressed (cassette side at the rear, disc side at the front), the wheel increases in rigidity and reliability. This configuration allows:
- Better absorption of forces : the loads are better distributed, which avoids deformation and improves the durability of the wheels.
- Optimized power transfer : by pedaling, you lose less energy, because increased rigidity minimizes losses between the cassette and the wheel.
- Better comfort by reducing the vibrations and microdeformations of the rim, G3 shelving improves the quality of rolling, especially over long distances.
The concrete benefits of G3 shelving
Campagnolo's G3 technology brings many benefits to cyclists, whether they are competitors or passionate amateurs.
1. Increased rigidity for better efficiency
Thanks to Figure 2:1, the rear wheel is particularly rigid on the side of the cassette. This means that when you press the pedals hard, your effort is directly transformed into propulsion. This improvement is particularly noticeable during the re-launches and sprints.
2. More efficient braking
On the front wheels equipped with the G3, Campagnolo reinforced the disc side to better absorb the braking loads. This allows a better distribution of forces and offers increased stability, especially in technical descents where braking is intense.
3. Improved longevity
With better management of the tension in the spokes, the wheel suffers less stress and more slowly. As a result, G3-equipped wheels require less retouching and maintain their performance longer.
4. Improved riding comfort
The G3 design helps reduce the microdeformations of the live rim. Result? Less vibrations felt, which makes exits more pleasant, even on damaged roads.
On which wheels do we find the G3?
Campagnolo applies this technology to several high-end wheel models, mainly carbon:
- Bora WTO and Bora Ultra WTO : Aerodynamic wheels for cyclists looking for performance.
- Shamal Dual (and old generation): a versatile model ideal for endurance and gravel.
- Campagnolo aluminum wheels like Scirocco for those who prefer aluminum without compromise on technology.
Conclusion: The G3, a real plus for your carbon wheels
In short, Campagnolo's G3 shelving is an innovation that is not limited to aesthetics. Thanks to its unique 2:1 layout, it offers better tension balance, optimizes power transfer and improves driving comfort. Whether you're a competitor or a fan of long trips, this technology may well transform your experience on the road.
If you are looking for efficient and durable wheels, investing in a G3-equipped model is a great idea. Have you ever tested this technology? Share your experience in reviews!
