Using the Wahoo KICKR Climb is easy. First, make sure it's properly paired with your Wahoo KICKR Smart Trainer. Then, connect it to your preferred third - party app or device. When you start your indoor training session, the simulator will automatically adjust the grade according to the virtual route in the app. As for maintenance, keep it clean and dry. Regularly check the connections between the KICKR Climb, the trainer, and your device to ensure smooth operation. Also, store it in a cool and dry place when not in use. Remember, it only works with Wahoo KICKR Smart Trainers, so don't try to pair it with other trainers.
