Wahoo KICKR HEADWIND is a smart fan designed specifically for the needs of indoor cycling training. Wahoo KICKR HEADWIND is Bluetooth controlled with a small size and shape that is designed to fit conveniently within your indoor trainer set up. A targeted airflow pattern blows wind only over the rider with a range of airspeeds that can be controlled manually or by pairing with ANT+ heart rate monitor or directly with your smart trainer. Pairing with heart rate requires no Wahoo sensors with the device recognizing any ANT+ device. Once it is paired you can use the Wahoo Fitness app to set the fan strength related to your speed or heart rate. This means you can have more cooling as you work harder and less when you don’t need it. Wahoo KICKR HEADWIND is low on noise and requires little space. With speeds of over 30 mph 48 kph it is the ideal complement to keep you cool during the toughest training sessions. The HEADWIND unit also features additional sockets which allows you to plug in other devices and minimize the tangle of cords below your trainer.
