The Justo Trainer from Elite is a top-tier interactive trainer built to challenge us from the comfort of our homes, offering targeted training programs, incline simulation, and accurate measurement of important data. Equipped with dual ANT+ FE-C and Bluetooth, this trainer is able to connect to our favorite apps, software, computers, tablets, smartphones, and Apple TV to ensure we see all of our important data fields immediately. It is compatible with road, gravel, and mountain bikes with 5x130-135mm quick-release hubs and 12x142mm thru-axle hubs (adapters included), and is immediately able to ride with our own Shimano 9, 10, 11, and 12-speed road cassette. The Justo will measure our watts with the integrated OTS (Optical Torque Sensor) power meter, which measures our power with an accuracy of +/-1%. It also features ERG Mode data smoothing options, which include an easy start feature that allows us to immediately resume an interval if we stop pedaling. For a more realistic ride, the interchangeable Flex Feet replicate the natural pressure and oscillations of our bike to adapt our indoor trainer to our on-bike pedal stroke, in turn reducing muscle fatigue and improving our overall efficiency.
