Marin offer a lifetime warranty on rigid frames and a 5-year warranty on full suspension frames for the original owner. Like our other brands, the warranty covers material defects and workmanship but not wear and tear, crash damage or poor maintenance! The lifetime warranty on rigid frames (for our purposes, hardtails), has the caveat that bicycles have an unquantifiable useful product life. The useful life span of a bicycle is affected by riding style, riding conditions, frame material and construction, and other factors. The warranty period offered by Marin does not guarantee that the bicycle will last forever, or for the life span of the original purchaser. You can read the full Marin Warranty policy here.
