Maintenance and Care for a FLUX Series Smart Trainer

FLUX Smart trainers are designed to be maintenance free.  Over time it is possible for the trainer to generate a bit of noise.  This FAQ is designed to solve most noise related issues.

A cracking sound when riding can be due to the need for the axle and cassette body needing grease.  In addition we also recommend the cleaning of the cassette.  This process should be performed on an annual basis.
