You can just ride the recalled fork, I'm still riding mine and its got almost 5k miles on it since 2017. If it hasn't broken yet its highly unlikely to considering they couldn't replicate the failure or determine the defect on the single failure. Forks can fail in the field for a number of reasons and I'm thinking cannondale is recalling the forks out of an abundance of caution. There are literally thousands of these forks that have been ridden and raced over the past 5 or so years
