    Campagnolo Chorus Ultra Torque Carbon crankset

    For many enthusiastic fans, it has always been an ambition to mount a Campagnolo drive system on their bike. The launch of the new mechanical shifting systems and the associated technical innovation and aesthetics further strengthen this desire. Ultra Torque semi-axles offer a low Q-factor and more freedom of movement for the ankles while riding. Despite the narrow side profile, the bearings could be positioned outside the bottom bracket shell, resulting in greater axle rigidity and maximum stiffness from the increased axle diameter. Modified chain lifters at the chainrings offer smooth shifting processes when the chain moves up and down in any chainring combination. · Ultra Torque technology for maximum stiffness · Ultra Hollow technology (hollow crankarms) · especially designed crank spider, chainrings are directly screwed to the crank · material crank: carbon · material chainring: light metal · material axle: steel · for 11-speed Campagnolo systems · weight: approx. 685 g · without bottom bracket cups, incl. Ultra Torque sealed bearings Please note: The crankset can also be used with front derailleurs of the 2014 series. The performance then corresponds to the 2014 components. With components of the 2015 series, maximum performance is achieved.

    Rotor 2INpower power meter

    The Rotor 2INpower crank-based power meter offers ambitious athletes and pros a dual-sided power measurement thanks to a combined strain gauge system in crank axle and right crank arm. Four strain gauges placed in the right crank arm and four in the crank axle independently measure left and right side power, analyse the values and transmit all data on power, cadence, balance, torque efficiency and pedal smoothness to the end device. The data can either be transferred to a smartphone with a respective cycling app via SmartBluetooth (update required) or to a bike computer via ANT+. Besides, the 2IN power power meter comes with a special analysis software that can even help you find the perfect pedalling technique when used on a desktop computer or notebook (PC or Mac). Graphical tools like OCA (optimum chainring angle) and Torque 360 help you assess force variations in your pedal stroke.

    Rotor 3D30 INpower crank-based power meter

    It's the INner values that count! As the electronics are integrated inside the axle, the INpower is completely shock-resistant and waterproof. The ROTOR INpower technology with integrated power measurement will improve the quality of your training as well as your experience. It is one of the lightest cranks with integrated power measurement and represents the perfect entry into power-based training. Well protected from shocks and contamination, the electronics are placed in the centre of the axle to ensure a precise and reliable data transfer. By measuring your power within a pedal stroke, the OCA (optimum chainring angle) system helps you to find the perfect OCP set-up (optimum chainring position) of oval Q-rings (not included). Data is smoothly transferred to a compatible end device such as the Garmin Edge 1000 via ANT+. The standard AA battery can be removed and replaced easily without any tools. The UBB bottom bracket philosophy allows you to combine the crank system with different frame standards: · Bold circle diameter: 110 mm/5-arm · Material: aluminium 7055, hollow forged · ANT+ data transfer to bike computer or GPS device, e.g. Edge 1000 (item no.: 2097310) · Measurement of cadence (without magnet), power in watts (Ø, max.), torque effectiveness (ratio of average torque to maximum torque in %), pedal smoothness (smooth pedal stroke); as the INpower measurement technology measures the power transfer to the left side, the left/right power balance is determined based on the values measured · INpower software to optimize your performance and to adjust the Q-ring position, available for free on www.inpower.rotorbike.com (Please note: The PC/laptop you would like to use the software with should have an ANT+ interfacem an ANT+ dongle is not included.

    Rotor Flow INpower MAS compact crank powermeter

    The aerodynamic profile of the crank arms has been optimized for a smoother pedal stroke by taking into consideration the changing air flow starting at the axle and flowing through to the pedals. For this, spider and crank arms have been developed separately in the wind tunnel using the Computer Fluid Dynamics (CFD) design software to achieve best aerodynamics. Perfectly suitable for use on time trial, triathlon bikes and in competitions. Despite this special optimization, the stiffness coould be improved, too. The core of the INpower measurement technology centered in the crank axle to protect it from shocks and dirt and to offer accurate and reliable data transfer. By analysing your power within one pedal stroke, the OCA (Optimum Chainring Angle) system allows you to adjust oval Q-Rings (not included) to the OCP (Optimum Chainring Position). This is possible thanks to the analysis of your training data with the INpower software. In combination with the right Q-rings, the MAS spider with several holes allows you to adjust the torque effectiveness even more precisely than classic spider mounts would, which helps you to develop a smooth pedal stroke. This results in an optimization of your pedalling movements while eating miles or doing interval training, which has a positive effect on your performance during competitions, too. · bolt circle diameter: 110 mm/5-arm · material: aluminium 7075 T6, CNC treated, Trinity Drilling system to hollow out the crank arms · ANT+ data transfer to bike computers or GPS, such as Edge 1000 (item no. 2097310) · measurement of cadence (without magnet), power in watt (Ø, max.), torque effectiveness (relation max. to Ø torque in %), pedal smoothness (smooth pedal stroke); as the INpower powermeter only measure the power on the left side, the right/left power balance is interpolated · INpower software to improve your performance and to support the adjustment of the Q-ring position, free download on www.inpower.rotorbike.com (Please note: the PC/laptop you want to use the software on must have an ANT+ interface, an ANT+ dongle is not included.
