Cedrus offers a limited lifetime structural warranty on Evolution masts. This does not cover impact, bottom strikes, excessive UV exposure, or letting your foil wash up in the shore break. As mentioned in the Owner's Info Page, the mast should last a lifetime if properly cared for. 

If we find that a Cedrus mast has failed due to manufacturing defects, we will at our option repair it or replace it. For normal wear and tear, corrosion, or finishing related issues, we will evaluate such instances on a case-by-cases basis and offer repair or refinishing services at our cost.

The same goes for adapter, however, adapters can be considered wear items, due to the nature of their use. Connecting the fuselage over years can wear the interface, and corrosion is more likely to occur if connected to a carbon fuselage. Just like you replace tires on your bike, you may need to replace adapters on your mast due to fatigue, corrosion, or abuse loads (bottom strikes).

Additionally, please note that foils and fuselages that connect to our adapters using M6 hardware (or equivalent) may lack necessary strength, and as this is a design feature which is beyond our control, failure of this nature will not be considered a warranty covered issue.
