Designed to fit inside the bottom bracket shell between bb cups, to stop internal cables fouling and being damaged by the crank axle.
Painstaking work was carried out on the sprockets. The additional speed led Campagnolo to devising a new support structure for the last six sprockets in the two subsets. The form of the teeth is new and they have been treated to increase duration over time. Eleven sprockets that are even more efficient despite the reduction of the thicknesses? Campagnolo have succeeded. The teeth have been designed to optimize the speed and fluidity of shifting. This form reduces stress on the chain which ascends more easily onto the higher diameter sprockets. The large pinions are divided into sets of three and are mounted on a new aluminium frame. Thanks to this, rigidity increases 180% and the individual sprockets are 70% more resistant to torsion.

The perfect coupling between central pin and pedal crank is ensured thanks to the particular geometry of the two components; this solution also makes it possible to eliminate the potential play between the different materials. To make the bottom bracket more efficient, they also worked on the inner part. Thanks to an elaborate sequence of thicknesses, they were able to obtain an incredibly light axle while offering an absolute response in terms of rigidity. Thanks to the studies conducted by the Campy Tech Lab engineers, material was removed in the zones that could be lightened but at the same time the points of maximum stress were strengthened. Only in this way was it possible to achieve such a high technical value. A careful working out of the dimensions made it possible to maintain the lateral measurements already defined with the "elder brother" Ultra Torque, thus guaranteeing the maximum freedom of movement and reducing the possibility of contact with the shoes.
These new cassettes are based on a design with one triplet and 8 single sprockets with aluminum spacers and will be compatible with the rest of the range (aside from the 11-32). The 11-32 cassette signals the introduction of not only a new, lower gearing cassette, but also a new range of cassettes which are labelled "Campagnolo 11" and are available in the following combinations: 11-25, 11-27, 11-29, 12,27 and 11-32.
The sprockets must be shaped appropriately for the drivetrain to work perfectly. Each sprocket on this Campagnolo 10-speed cassette has an indented ramp, called Ultra Drive (UD), to assist in upshifting. The Tooth profiles are also custom configured to help with downshifting. The end result is perfect shifting and high-precision operation on every ride. Please Note: Not compatible with the Wahoo Kickr turbo trainer as this cassette has 8 inner arms. The Wahoo Campagnolo Freehub is only compatible with 4 arm Campagnolo cassettes.

These are the official 11 speed jockey wheels for us with their Super Record rear derailleur. A must have purchase to ensure your derailleur runs fast and effectively.
Skeleton geometry has made it possible to reduce weight without diminishing braking power while maintaining the same operating safety. The differentiated front and rear geometry ensures power and progressive travel. brake-pad height adjustment ratio: 40-50 mm (measured from brake fixing-bolt to brake-shoe-nut)
Ultra Shift ergonomics This ensures a firm grip on the handlebars and fast, precise control of the levers. The special ergonomic design makes it possible to assume three different hand positions on the levers compared to the two traditional ones.
The completely redesigned rim for the Campagnolo Zonda C17 road wheels takes its design inspiration from the growing trend that sees the use of increasingly wider tyres, with 25mm clinchers becoming the standard if not the new minimum sizing for road riding and racing. With this increased popularity of both 25mm and 28mm tyres, the wheel needs to be designed in a way to optimise the tyre/wheel interface. The updated wider rim on the Campagnolo Zonda C17 wheelset ensures a more efficient shape of the tyre, improving cornering grip and safety while reducing aerodynamic drag and rolling resistance. This seemingly small increase in width offers a surprisingly different riding experience, one that is sure to leave any cyclist pleasantly convinced that this change is for the best. The C17 rim has also been structurally optimised and ensures a surefooted grip on clincher tyres, as well as even better braking, feel when compared with previous versions.

Born as the very first complete wheelset with each component in its build being specifically designed as a complete unit to ensure unparalleled efficiency and performance the Shamal continued to introduce new technologies that would change the way aluminum performance wheels were produced. So advanced was the Shamal in its early stages that it was found also in World Tour competition often and to this day is still perhaps the most race ready aluminum wheelset available.
