Campagnolo Zonda GT C23 DB 2-Way Fit AFS wheelset

Maximum all-road versatility: ideal for both wider gravel tyres and thinner road solutions.

The ZONDA GT wheel features an excellent combination of Campagnolo's best technologies, offering maximum versatility in the choice of tyres to match - from gravel to road. The iconic G3 spoking and the striking anodised finish give the ZONDA GT aluminium wheel its refined look and clearly identify the wheel as a Campagnolo product. Weighing only 1690 g (manufacturer's declared weight) thanks to the strong but light aluminium structure and Campagnolo's patented N3W body. The 23 mm internal width expresses the wide versatility of the ZONDA GT: a wheel that fits both wider tyres for dirt and gravel tracks and thinner road tyres.

Assembly
The Zonda GT DB wheel is completely hand-assembled by a specialised Campagnolo operator and is 100% controlled using electronically controlled instruments. This procedure guarantees the maximum performance and reliability of all Campagnolo brand wheels.

Milled rim
This machining makes it possible to reduce the perimeter weight of the rim, making the wheel extremely reactive.

RDB™ - Rim Dynamic Balance
The concept is simple and elegant: balance the weight of the valve with a similar weight on the diametrically opposite side.

Momag™
Allows an external rim profile without holes, improving both rigidity and weight.

Spokes
G3™ technology also applied to the front wheel to improve performance under high braking power.

Front wheel spokes
24 stainless steel spokes with a 1.6 mm round section

Rear wheel spokes
24 stainless steel spokes with a 1.6 mm tapered circular cross-section.

Self-locking nipples
Black anodised self-locking nipples on the outside of the rim for easier maintenance.

Cone/shield bearings
Easy adjustment of the bearings reduces possible play while maintaining constant performance over time and ensuring an optimum contact angle between the ball and surface.

Adjustment ring
For precise adjustment of the hub to prevent play.

2-WAY FIT™
2-WAY FIT™ is the innovative profile that makes it possible to fit both a tubeless tyre and a classic clincher. Thanks to 2-Way Fit™ technology, those who choose Campagnolo® wheels will have the opportunity to personally test which of the two solutions they feel most comfortable with, or to use the clincher for training and the tubeless tire for race day. There is no doubt that tubeless is the future of road cycling tyres. In addition to greater comfort, the big advantages are: by using a tubeless tyre you can take advantage of the greater smoothness due to the absence of friction between the tyre and tube. A tubeless tyre does not suffer from sudden deflation in the event of a puncture, a decisive advantage in terms of safety. The tubeless solution also eliminates any risk of pinching, because there is no inner tube. In the event of a tubeless tyre puncture, the Campagnolo® 2-Way Fit™ system makes it possible, by simply removing the hermetic closure valve, to fit the classic inner tube and continue pedalling without any problem.

N3W
N3W, which stands for NEXT 3 WAYS, is a patented standard freewheel body engineered to accommodate 11, 12 and 13-speed cassettes with 9, 10 and 11-tooth starts, while maintaining compatibility with older 9 and 10-speed cassettes. To make it compatible with all current 11-tooth start cassettes, simply use the N3W ring (ring + lockring kit cod. AC21-N3W), which restores the length by aligning it with that of the classic body. N3W is directly compatible with the new Campagnolo 9- and 10-tooth start cassettes. N3W has the same spline profile as the Campagnolo classic body, but with a considerable weight saving, thanks to a 4.4 mm shorter length. The N3W Light version features an aeronautic-quality aluminium hub, modelled on optimised geometries, offering maximum torsional stiffness and maximum performance control. The special Campagnolo machining thus gives shape to a patented Next 3 Ways freewheel body with unrivalled smoothness and lightness. The N3W freewheel body can be found in the carbon wheels for Bora WTO, Bora Ultra WTO, Hyperon Ultra racing bikes and for the Shamal Carbon wheels.

G3 spoke geometry
Campagnolo's iconic G3 spoke geometry is a challenge to the conventional configuration of racing bike spokes. Groups of three parallel straight-head spokes are in fact arranged in a 2:1 ratio. Having twice as many spokes on one side enables wheels with G3 technology to achieve the perfect balance of tension, increasing stiffness and improving power transfer. This unique and iconic design helps to improve load absorption and reduce weight. The G3 spoke pattern also positively influences the riding experience: the original triplet pattern reduces perceived vibrations, minimising micro-deformations of the rim under tension and its response to the stresses of the course. The G3 geometry is designed with optimised solutions for the front wheel and rear wheel. The front wheel sees a higher number of disc-side spokes to absorb braking loads. At the rear, on the other hand, the same loads are transferred to the doubled number of spokes on the cassette side through the monolithic hub body: an intuition that allows both braking and power transfer during pedalling to work. G3 spoking can be found on the Bora WTO racing wheels, Bora Ultra WTO, Shamal family wheels and on all the aluminium wheels of the Campagnolo collection.
