Campagnolo Bora Ultra 50 Clincher Rear Wheel

Innovating the wheel that for years has been a market benchmark might have seemed difficult and risky, but the Campy Tech Lab designers have managed to maintain those characteristics of flexibility and ease of handling that have made this high-profile wheel easy to steer, high performing and safe.

The new Bora Ultra 50 bursts onto the market not only with introduction of the new tyre bed dedicated to the clincher, but also with improvements to the previous version in terms of lightness, aerodynamics, stiffness and comfort thanks to use of the new wider rim and front and rear hubs with different diameters.

The 2018 range sees the addition of the new AC3 (All Conditions Carbon Control) Technology braking track, which brings braking safety on wet terrain closer to that on dry.

Plus extremely clean-cut aesthetics guaranteed by innovative water-transfer graphics. All without giving up on the extreme smoothness, which has become the market benchmark and is the result of use of CULT bearings.

Bora Ultra is the choice of the pros, the ideal competition wheel. They provide all the characteristics that every cyclist wants; maximum aerodynamic performance, extreme lightness, surprising reactivity combined with incredible smoothness.

The secret of this legendary wheel lies in the details and the innumerable victories are its best testimony. The Bora Ultra wheel is entirely hand-assembled by a specialised Campagnolo technician and is checked in every tiny detail with electronic instrumentation. This ensures maximum performance and reliability for all Campagnolo wheels.

Technology

USB Ultra Smooth Bearings

Perfectly smooth surfaces and lower friction to reduce loss of power are the most interesting features.

Add on the reduced weight and resistance to corrosion and you will understand why Campagnolo can give you the best thanks to USB. All your power will be transferred onto the road.

Campagnolo has a long-standing reputation for the extremely high performance of its hubs in terms of smoothness and reliability. In fact, all the projects are entirely developed in our R&D department Campy Tech Lab and Campagnolo have put obsessive care into taking care of every detail.

The hubs with USB ceramic bearings (Ultra Smooth Bearings) further enhance the wheels' smoothness and reduce weight and the need for maintenance. Comparative tests have shown that USB bearings are 50% smoother than standard bearings.

Now improving your performance during the race or simply going for a ride with your friends will be easier.

USB - Ultra Smooth Bearings - technology is used for Record cranksets and for the new Shamal Ultra wheels.

G3 Geometry

Campagnolo’s unique G3 spoke pattern comprises groups of three parallel straight-pull spokes, arranged in a 2:1 ratio. Having twice as many spokes on one side allows wheels with G3 to counteract the asymmetric drivetrain and braking forces acting on them, creating more symmetric performance and equalising the load. Energy transfer and lateral rigidity are improved, and spoke tension is optimised, reducing stress and increasing lifespan.

All Campagnolo disc brake wheels utilise the G3 pattern, the front wheel has more spokes on the disc brake side, and the rear is biased to the drivetrain side.

Dynamic Balance

RIM Dynamic Balance – aluminium wheels

The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side. For top models, this is obtained by a special operation on the section of the rim opposite the rim joint.

Spokes Dynamic Balance

For entry-level models, Dynamic Balance is obtained by using two oversized spokes in the section opposite the joint. The result is a wheel with perfectly balanced rotational dynamics.

RIM Dynamic Balance – Carbon wheels

For carbon wheels the principle is the same, but applied using a different technology. When making carbon rims, the pieces of carbon fabric are aligned in such a manner that the resulting rim is always balanced.

AC3

It is a general consensus of opinion within the cycling world is that one of the major drawbacks of the carbon fibre racing rim is the reduced rim braking performance in the wet. To combat this problem Campagnolo has developed the All Conditions Carbon Control, or AC3 Technology.

The introduction of the meticulously researched textured design of the rim brake area creates a surefooted stopping power that is reliable and potent no matter what the weather will throw at you. On the Campagnolo Bora rim brake wheelset range, under dry conditions, the new technology increases braking performance by 3% compared to the previous Bora while increasing the distance from its closest competitor by over 6%. However, it is when the weather conditions deteriorate that the AC3 technology permits the Bora to excel increasing braking performance an astonishing 43% over previous Campagnolo models.

The powerful braking of AC3 represents a nearly 55% performance gap over that of its closest competitor making for a significant advantage when the heat of the race is on.

Campagnolo Wheel Identification Card

Since its birth over 80 years ago Campagnolo has been dedicated to continuous innovation in order to produce the best, most competitive and reliable products possible. To continually push the limits in this way is the work of the engineers of the Campy Tech Lab. Even the smallest details and material choices are painstakingly scrutinized in an effort to produce what is often to become the newest performance standard. As a result, our testing department is one of the most important areas of the entire operation and each and every product must go through strenuous and extreme testing before it earns the right to bear the Campagnolo name. Campagnolo test at levels above and beyond anything required and as a result produce products that are a step ahead.

• Fatigue test: before the manufacturing stage, each wheel and each of its components are subjected to long and very challenging tests that ensure the durability and performance over time.
• Crash test: simulates the impact of the wheel in differing situations. Campagnolo crash tests have successfully passed all requirements stipulated by the UCI.
• Tyre burst test: all Campagnolo wheels are tested at inflation pressures well above those indicated on the tyre.
• Environment test: exposure to UVA and UVB rays, salt attack and exposure to moisture: these are the tests that all Campagnolo wheels must pass to ensure maximum performance and reliability over time.

100% Manually assembled and Electronically checked.

The extensive attention to detail and testing mentioned above may be sufficient for some companies to ensure the quality of their product but not for Campagnolo. To ensure the quality of each and every wheel the standards applied to the production process must be then verified on each and every final product at the end of fabrication. Campagnolo made a clear and bold decision: to assemble each wheel manually and submit it to a series of final inspections that guarantee their quality.

Only through in-depth inspection, both manual and digital, of each and every piece of every final product that leaves the premises can Campagnolo be 100% sure of the exact same quality for each and every wheel that bears the Campagnolo name.

• Balancing: guarantees the absence of vibrations at fast speed.
• Lateral and radial control: guarantees the perfect alignment of the wheel to ensure precise rolling of the wheel.
• Camber: ensures the perfect symmetry of the wheels with the bicycle.
• Spokes tension: ensures optimal balance at every point of the wheel.
• Rolling torque of the hub: ensures a perfect adjustment of the hubs.

Certilogo

Campagnolo and Certilogo against counterfeiting: a tangible answer that protects our clients’ safety and purchases.

Top-end Campagnolo wheels are considered by the market and by afi cionados to be reference products and as such are highly desirable. They have therefore also become appetising to counterfeiters who have cloned some of our models (especially those in carbon fibre) releasing considerable numbers onto the international markets. The wheel is a performance product, but also a safety component. This aspect means that those who purchase a fake product, while saving money on something that clearly costs much less than the going market price, puts their personal safety at great risk. The materials and production processes that together help to achieve a safe performing product are obviously not the same.

With the aim of fighting and combating these counterfeiters, Campagnolo is the first in the cycling sector to have put in place, thanks to the support of Certilogo, a control system that enables our clients to authenticate the product simply and immediately.

Starting with the products in the 2015 catalogue, each pair of Campagnolo wheels in the Bora and Hyperon lines will come with an individual ID code (the Certilogo Code or CLG Code) on a swing tag attached to a spoke on the wheel and, from July 2018, on an adhesive stuck to the rear wheel.

The Certilogo Code (in both numerical and QR code format) will allow anyone, before or after purchase, to check that the product is authentic. To authenticate Campagnolo wheels, just visit www.certilogo.com, insert the CLG Code or download the Certilogo APP.

We suggest you keep the Campagnolo Original Wheels tag even after product authentication for possible future use and, for wheels bought from July 2018 on, leaving the sticker with the Certilogo Code on the wheel.
