Auto pause: It stops computing when you come to a halt. . * Magnet-free sensor: An innovative sensor that fits on the wheel hub and detects speed using a magnet-free gyroscope. It's therefore really easy, fast and reliable to install. 2.4 GHz digital transmission. No interference possible. Communicates with the cyclometer over up to 3 metres. You can therefore mount it on the rear wheel and use it with a turbo trainer. CAUTION This technology is not compatible with excessively uneven terrain and may not display correct speeds until the values have stabilised. * Hubs compatible with the speed sensor: The box contains several sizes of elastic: First size of silicone elastic: hub diameter 24 mm ~ 32 mm, maximum diameter = 34 mm Second size of silicone elastic: hub diameter 19 mm ~ 23 mm, maximum diameter = 25 mm * Size adjustment of the wheels: Sensor compatible with 12" to 29" wheels, i.e. a circumference (L) between 935 mm (12×1.75) and 2326 mm (29×2.3).This covers your kids', road, MTB, 650C and 700C bikes.
