Somewhat, but considerably less than clipless. Unless physically damaged, the REMmagnets’ pull force will last a lifetime. So to protect the magnets we coat them entirely in a nickel/zinc jacket and then cover both ends – where the REMplate™ contacts the REMmagnets – with stainless steel caps. If the magnets still manage to get chipped or otherwise damaged, and the neodymium is exposed, it may oxidize and become increasingly brittle. This is rare but can happen over time with excessive erosion from dirt and sand under the shoe, so keep an eye on the plating.
