The trainer does not need a lot of maintenance. It is very important to keep the roll clean from any rubber residue that might come from the trainer.
Training tyres will prevent slip and heat. It is very important that you use one. Other tyres are causing heat issues and can make the metal plate come loose from the softgel roll. After one year the tyre can be dried out. That is why we advise to use each year a new trainer tyre.
