The Wahoo Kickr AXIS Action Feet are a set of accessory feet designed to be used with the Wahoo Kickr smart trainers. They offer a more realistic riding experience by allowing the trainer to move with the natural motion of the rider, simulating the feeling of riding on the road. The AXIS feet feature three different stiffness levels (soft, medium, and firm), allowing riders to customize the feel of their trainer to suit their preferences. The feet are easy to install, simply replacing the standard feet on the trainer. They are also compatible with the Wahoo Kickr Core and Kickr Snap trainers, providing an enhanced riding experience for a wide range of cyclists. NOTE: KICKR AXIS is NOT compatible with KICKR CORE and KICK SNAP
