Bora Ultra WTO 45 C23 Disc Brake

H.U.L.C. (Handmade Ultra-Light Carbon) is the exclusive Campagnolo technology for the production of carbon rims that optimizes the carbon fiber and resin ratio to increase stiffness and control. This distinctive feature of top-end Campagnolo wheels is an evolution of the exclusive carbon molding process patented by Campagnolo that creates defect-free rims and requires no additional coats of lacquer. Optimization of the carbon fiber and resin ratio guarantees a reduction in weight and unprecedented dimensional accuracy of the safety elements on the 2-Way Fit rim (coupling diameters, hooks and humps). H.U.L.C. technology is applied to Bora Ultra WTO, Hyperon Ultra, Shamal, and Ghibli wheels for racing bikes and to Levante gravel wheels.

Campagnolo’s iconic G3 geometry challenges the conventional configuration of wheel spokes on racing bikes. Groups of three parallel straight-pull spokes are in fact arranged in a ratio of 2:1. Having twice as many spokes on one side allows wheels with G3 technology to achieve perfectly balanced tensions, increasing stiffness and improving energy transfer. An iconic design with unique style that helps to improve load absorption and reduce weights. The G3 spoke pattern also has a positive effect on the steering experience: the original triplet pattern reduces perceived vibrations, minimizing micro-deformation of the rim under tension and its response to stressors on the course. G3 geometry is designed with optimized solutions for front and back wheels. The front one has more spokes on the disc side to absorb braking loads. Whereas on the back one the same loads are transferred to twice the number of spokes on the cassette side through the monolithic hub body: an intuitive idea that enables functioning during both braking and energy transfer during pedaling. The G3 spoke pattern is used on Bora WTO and Bora Ultra WTO racing wheels, wheels in the Shamal family and on all the aluminum wheels in the Campagnolo collection.

The innovative Campagnolo Mo-Mag system means that the nipples can be positioned inside the rim using a magnet, without the need to make additional holes in the bed and in this way offering the safest, most user-friendly tubeless compatible system on the market. Aero Mo-Mag now takes this one step further, with a completely internal hidden system that maximizes aerodynamics and enables the construction of a lighter rim; a single piece of carbon with just one join in the fiber. The internal fiberglass-reinforced polymer seats for the nipples have been specifically designed for every possible combination of rim and hub to achieve perfect alignment of the spokes and nipples and a huge reduction in stress during use on each component. Spoke tension can be adjusted easily, even using the conventional method with the Torx tool that comes with the wheels. Aero Mo-Mag technology is used on the famous Bora Ultra WTO carbon wheels for racing bikes and Hyperon Ultra wheels.

The iconic CULT—ceramic bearings for Campagnolo racing bike wheels—are only mounted on the best hubs and cranksets and are revolutionary compared to other bearings on the market. Thanks to their properties, produced to specific Campagnolo design, CULT bearings offer extremely low friction, enabling maximum performance and energy savings when pedaling. The top-quality ceramic balls with high-precision roundness and resistance turn inside polymer cages on stainless steel races that are extremely resistant to wear and tear. These cages are designed with tolerances accurate to the micron, which maximizes their efficiency and durability. CULT bearings do not deform or corrode, ensuring long-term constant performance and product quality. Their maintenance requires only periodic cleaning and light lubrication with synthetic oil. CULT bearings have a 40% lower friction coefficient than standard sealed bearings and they roll for 5 and a half times longer in tests. CULT ceramic bearings are available for the best-known Campagnolo racing bike wheels: Bora Ultra WTO, Ghibli and Hyperon Ultra.

N3W stand for NEXT 3 WAYS, a patented standard for a freewheel body engineered to house 11-, 12- and 13-speed cassettes with 9-, 10- and 11-tooth starting sprockets that is still compatible with older 9- and 10-speed cassettes. To make it compatible with all of today’s cassettes with 11-tooth starting sprockets, simply use the N3W ring (kit complete with ring + ring code AC21-N3W), which makes them the same length as the classic body. N3W is directly compatible with the new Campagnolo cassettes with 9- and 10-tooth starting sprockets. N3W has the same groove profile as the classic Campagnolo body but it is 4.4 mm shorter, making it much lighter. There is also a N3W Light version with an aeronautical-quality aluminum hub with optimized geometrics that delivers maximum torsional stiffness and maximum performance control. Special Campagnolo processes have resulted in a patented Next 3 Ways freewheel body with unmatched smoothness and lightness. The N3W freewheel body is used on Bora WTO, Bora Ultra WTO, and Hyperon Ultra carbon wheels for racing bikes and on Shamal Carbon wheels.
