Campagnolo Bullet 50 Rear Wheel

The Bullet is not just beautiful: behind its bold and aggressive design, this wheel offers new technical innovations and first class performance. A carbon wheel with all the benefits of the aluminium braking track: responsive and agile when needed, comfortable on any kind of ride.

The Mega-G3 Spoke pattern is a type of spoke assembly that improves energy transfer between the hub, which reduces stress on the right-hand side which in turn increases the rigidity of the wheel. This is achieved by having twice as many spokes as the left-hand side.

Technology

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 scrutinised 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 entyre operation and each and every product must go through strenuous and extreme testing before it earns the right to bear the Campagnolo name. Campagnolotest 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 Campagnolobe 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.

Features

Integrated Aluminium / Carbon Rim Structure

The exclusive coupling system of the aluminium rim and carbon structure makes the rim extremely rigid, it allows for excellent responsiveness levels and durability of the wheel.

Dynamic Balancing On The Rim

Thanks to a special operation of the production process, the carbon fibre layup is positioned in such a way as to obtain perfect balancing of the rim even at high speeds.

MOMAG

The external rim profile is free of holes, so the structural integrity of the wheel is increased and there is no need for rim tape.

DRMC (Directional Rim-Spoke Coupling)

System for equal tension and correct alignment throughout the wheel (including the rim, spokes, nipples and hub).

Aluminium Hub Body

Gives the wheel a high degree of lateral stiffness and reduces weight to the minimum.

Oversized Flange On The Drive Side

Increases the torsional stiffness, increasing reactivity at each change in rhythm of the pedal stroke.

Spoke Anti-Rotation System

Keeps the spokes in the position of maximum aerodynamic penetration.

DRSC (Directional Rim-Spoke Coupling)

Exclusive rim/spoke coupling system. It allows the rim, spokes, nipples and hub to align properly with the same tensioning value in all areas.

Aerodynamic Profile In Steel

Ensuring the maximum aerodynamic penetration and, thanks to the material employed, lower weight and greater reactivity.

Self-Locking Nipples

It allows to maintain the right tension of the spokes and does not require any maintenance.

Quick Release

New, completely redesigned and lighter wheel block Steel spine and eccentric, lever with drill lightening and aluminium die.

Eccentric-closure system allows cyclist to modulate the pressure necessary for heightened sensitivity to find the proper closure for the block. Easy to use, with a material resistant to wear and tear, rust, and pressure.
