This bike is supplied with a 6 month warranty which covers manufacturing defects. Warranty does not cover mistreatment or poor maintenance. The owner is responsible for ensuring that components are not allowed to come loose as this increases the chance of damage to threads and tapers. It is recommended that owners check that their bike is in good working order before and after each ride - trials bikes are more prone to parts becoming loose because of the type of riding they are subject to.
