The evolution of precision; the Justo will take your training to the next level.Elite's most accurate trainer, refinements to both the firmware and internal components yield an industry-leading power accuracy of 1% via Elite's proven Optical Torque Sensor (OTS) system. These developments also allow the Justo to be the first Elite interactive trainer with automatic calibration, no manual calibration by the user is required to ensure precise operationNew flywheel design is not only heavier at 6.2 KG for improved ride feel, but more aerodynamic, to reduce noise, this makes the Justo our quietest ever trainer,Includes 2 sets of Flex feet to allow the trainer to move in use for a more natural feel,or to be fixed in place if that is prefered,Dual Bluetooth channel allows the Justo to be used both as a cadence or cardio bridge with compatible wireless accessories (not included) and with both the latest Bluetooth standards and ANT+ FE-C connections available the Justo has the widest possible compatibility,Sustainable construction; most of the trainer is made from reusable metal or recycled materials to reduce the trainer's initial environmental impact and to assist in end-of-life recycling,Compatible with Shimano HG 11-speed cassettes (not included), conversion kits available for Campagnolo, SRAM XDR or MICRO SPLINE,Compatible with 142 x 12 and 130/135 mm Q/R frames out of the box , adaptors available for 141 mm QR, 148mm Boost and 157 mm Superboost.Justo is equipped with a new more sensitive OTS sensor that improves the overall accuracy by 33% compared to Direto XR-T (from +/-1,5% to +/-1,0%),especially in low torque conditions(low power / high speed). This also allows Justo to simulate lower slope gradients at high speed.The Elite Flex Feet deliver the most realistic ride feel by replicating the side-to-side movement experienced riding outdoors. Justo comes with a set of Elite Flex Feet offering two stiffness options to truly tune your ride to your unique body structure, riding style and indoor training set-up. Thanks to the new Auto-Calibration Technology, Justo continuously offers accurate and precise power data eliminating the need of manual intervention by the user. You can also use Justo in stand-alone mode, that is, when it is not connected to an app either if powered or not.
