Intended use

ROCKERON™ Axis is a modular rocker plate feet system for indoor smart trainers. It enables controlled side-to-side movement to improve comfort and ride feel during indoor training.

Important: This product is not a toy. Not suitable for children under 14 years of age.

Before installation

Before installing ROCKERON, make sure the smart trainer is not mounted with a bicycle or any other training equipment. Handle the smart trainer with care. Place it on a carpet or a similar soft surface. Tilting the trainer onto its side during installation may be helpful.

General installation steps

1

Remove the original rubber feet

Completely remove the original rubber feet from the smart trainer. Some smart trainers use screws on the underside of the rubber feet. If so, unscrew the original screws from below and keep them for installation.

2

Install the Axis elements

Slide the ROCKERON Axis elements onto the two trainer axles. Make sure each element is positioned correctly.

BR = Back Right
BC = Back Center
BL = Back Left
FR = Front Right
FC = Front Center
FL = Front Left
Note: Screws Versions: The elements BR, BL, FR and FL must be fixed to the smart trainer using the original screws removed from the rubber feet.
3

Install the metal rod if included

Some ROCKERON Axis models include a metal rod. Insert the metal rod through the designated holes and secure it with washers and nuts.

Tip: You can attach one washer and nut to one side before inserting the rod.
4

Insert the Motion Balls

Insert the Motion Balls into all ball housings of the Axis elements according to your selected setup.

Important: All external ball housings must always contain a ball. Never use the system without balls.
5

Install the front support

Use the matching front riser or Zwift Ride front adapter for your setup. Make sure the front support sits securely on a flat surface.

6

Check stability

Ensure that all adapters are properly seated and that the trainer stands securely on the floor before getting on the bike.

7

Start with an easy first ride

Ride gently for the first minutes and check that the movement feels controlled. Avoid hard sprints or abrupt movements during the first ride.

Motion Balls and ride feel

ROCKERON supports different Motion Ball setups to tune the ride feel. Start with the recommended setup before testing different configurations.

  • Yellow balls: more stable feel
  • Mixed setups: more adjustable feel
  • Additional ball sets: more tuning range

How to switch ball configuration

Switching Motion Balls changes how the setup reacts under load. For your first rides, use the recommended starting setup. Later, use the Pain Cave setup guide to test different configurations.

Note: Only change one side or position at a time when testing a different ride feel.

Safety and first-ride tips

  • Ensure that all components are properly installed before starting your training.
  • Use ROCKERON only on a flat, non-slip surface.
  • Regularly check the adapters for a secure fit.
  • Stop immediately if the setup feels unstable.
  • Re-check the Motion Balls after your first ride.
  • The maximum load corresponds to the usage specifications of the respective smart trainer manufacturer.
  • Use the smart trainer only as intended.
  • Do not perform jumps or abrupt, jerky movements.

Care instructions

Clean the components with a cloth as required. Avoid aggressive cleaning agents that could damage the material.
