Hammerhead Karoo cyclocomputer Limited Edition Force
The new Hammerhead Karoo is a milestone in terms of innovation, design and performance. It is equipped with an impressive smartphone quality screen with the best color display and an intuitive configuration of driving data and maps. The operation takes place through the reactive touchscreen or, alternatively, through the classic buttons. The combination of sophisticated design and innovative software makes the Karoo particularly intuitive. The fast quad-core processor with 4 GB of RAM guarantees fluid operation, short charging times and greater battery life. The 64 GB internal memory offers more space for maps, paths and training plans. Hammerhead offers the most agile software on the market. New features and improvements keep your device always updated. With Sram Force Shifter is possible. Thanks to the rigid brake pliers and the newly concept gearbox/brake levers with optimized hub point, it is possible to generate greater braking power in all the positions of the handlebar with a significantly lower force of the hand. Thanks to the ergonomic design and the adjustment of the handle of the handle, the change commands are comfortable to use for a wide range of hands. Another strong point are the additional gearbox buttons integrated in the-manubbri covers, which can also be used to operate the cyclocomputer compatible with Ant+. The main testurized change palette work according to the tested logic of Etap Cambiata. A balancing switch for the uphill change and one for the downhill change. By operating both palettes at the same time, the front derailler is operated. The behavior of the gearbox can be customized via the SRAM Axs app and it is also possible to integrate the SRAM BLIP wireless change commands. Bleeding Edge technology guarantees a simple and clean purging. Thanks to the thin design and carbon brake levers, the Force Axs HRD system is significantly lighter than the previous version.

Paceline Center lock brake rotors
Paceline brake rotors resume the elegant design of the Axs Road groups. Thanks to the optimized ventilation holes, they guarantee fluid braking and low vibrations. The rounded edges on the upper part of the rotor reduce the risk of injuries to a minimum and comply with the guidelines of the Cycling Association UCI. Another advantage is that they facilitate the assembly of the wheels, since the rounded upper part prevents the jam in the brake caliper. Thanks to a narrower cage with an optimized shape, the change on the large crown and under load are even more reliable than the previous version. The front derailler is designed for the 2 shades of SRAM X-RANGE CROND with 13 teeth between the large and small crown. Equipped with the tested Yaw technology and the Autotrim function, the front derailler works fluidly in any combination of relationships. The force during the change with an Axs command is automatically regulated on the entire change interval. The adjustment tool included in the package guarantees a perfect adjustment of the front derailler. The Etap wireless electronic change logic guarantees intuitive change processes and a simple and wireless configuration. Thanks to the integration of Axs technology, the behavior of the front derailler can be customized through the dedicated app. The necessary energy is provided by the tested SRAM Etap battery. The newly concept force rear derailler, with its carbon cage, saves 12 grams compared to the previous version. It can be used with boxes from 10-28 to 10-36 teeth, to be equipped for any land. The increased derailler's pulleys guarantee an even more efficient chain scrolling. Thanks to the profile of the X-Sync teeth and chain management technology, the chain is safely guided even in adverse road conditions. It is possible to accurately configure and adjust the rear derailler via smartphone via the SRAM Axs app. An ant+ transmitter integrated into the rear derailler allows communication between the cyclocomputer and the rear derailler. This allows you to view information on the battery charge status and on the current transmission ratio on the cockpit.

chain 114 meshes
thanks to the internal and external plates millions, SRAM has managed to save some gram of weight on the Force-Flattop chain. Thanks to the hard chrome coating on the internal plates and rollers, the chain also resists demanding changes and has a longer duration. The chain easily blocks with the Powerlock padlock included.

charger/batteries
The batteries integrated into the rear derailler and in the front derailler have an autonomy of over 1000 kilometers. The state of charge can be read at any time via LED lights. The batteries of the rear derailler and the front derailler are identical and can therefore also be replaced on the road. The batteries are recharged in an hour using the charger.
