G3 spoke pattern – Campagnolo
If you are interested in road racing wheels, you have probably already heard of the G3 spoke pattern from Campagnolo. This unique lacing stands out for its innovative spoke layout, which improves stiffness, power transfer and ride comfort all at once. But how does it actually work, and what benefits can it bring to your carbon wheels? That is what we are going to look at together.
What is Campagnolo’s G3 technology?
The G3 spoke pattern is based on an original layout in which the spokes are grouped in threes, instead of being spread evenly around the rim as on a traditional wheel. These groups of three spokes are organised in a 2:1 ratio: the wheel has twice as many spokes on one side as on the other. This design, patented by Campagnolo, is used on high-end wheels such as the Bora WTO, Bora Ultra WTO, Shamal and several of the brand’s aluminium models.
Why this 2:1 layout?
The idea behind this design is to balance the tensions acting on the wheel as well as possible. By increasing the number of spokes on the most heavily loaded side (cassette side at the rear, disc side at the front), the wheel gains stiffness and reliability. This configuration allows:
- Better absorption of forces: loads are better distributed, which prevents deformation and improves the durability of the wheels.
- Optimised power transfer: when you pedal, you lose less energy, because the increased stiffness minimises losses between the cassette and the wheel.
- Better comfort: by reducing vibrations and micro-deformations of the rim, the G3 spoke pattern improves ride quality, especially over long distances.
The practical benefits of the G3 spoke pattern
Campagnolo’s G3 technology brings several benefits to cyclists, whether they are racers or keen amateurs.
1. More stiffness for better efficiency
Thanks to the 2:1 layout, the rear wheel is particularly stiff on the cassette side. This means that when you push hard on the pedals, your effort is turned directly into forward motion. This improvement is especially welcome when accelerating and sprinting.
2. More effective braking
On front wheels with G3, Campagnolo has reinforced the disc side to cope better with braking loads. This gives a better distribution of forces and greater stability, especially on technical descents where braking is heavy.
3. Improved longevity
With better management of spoke tension, the wheel is under less stress and wears more slowly. As a result, wheels with G3 need less truing and keep their performance for longer.
4. Improved ride comfort
The G3 design helps reduce micro-deformations of the rim under tension. The result? Fewer vibrations felt, which makes rides more pleasant, even on damaged roads.
Which wheels feature G3?
Campagnolo applies this technology to several high-end wheel models, mainly in carbon:
- Bora WTO and Bora Ultra WTO: aerodynamic wheels for cyclists looking for performance.
- Shamal Dual (and the previous generation): a versatile model ideal for endurance and gravel.
- Campagnolo aluminium wheels such as the Scirocco: for those who prefer aluminium without compromising on technology.
Conclusion: G3, a real plus for your carbon wheels
In short, Campagnolo’s G3 spoke pattern is an innovation that is not just about looks. Thanks to its unique 2:1 layout, it offers a better balance of tensions, optimises power transfer and improves ride comfort. Whether you are a racer or a fan of long rides, this technology could well transform your experience on the road.
If you are looking for high-performance, durable wheels, investing in a model with G3 is an excellent idea. And you, have you already tried this technology? Share your experience in the comments!
