From DC Rainmaker Wahoo KICKR CLIMB In-Depth Review
And as for 3rd party trainers, that’s also a non-starter. See, Wahoo’s pairing process is only to their trainers. So the KICKR CLIMB pairs specifically to the trainer itself, rather than an app. That allows it to work out of the box with any app, as the app doesn’t even ‘know’ about the CLIMB. Instead, the app talks to the KICKR like it always has for years, sending it grade commands (i.e. 5% incline, or –2% decline). The KICKR/SNAP trainer simulates that grade and then wirelessly passes along that command to the CLIMB at the same time.
