I have an old and basic Fox Float R that, by and large, does what I ask of it with minimal complaints. However, once a year, like clockwork, when I choose to go riding in cold (~ freezing) temperatures, an internal seal perishes and I end up with air mixed in with the damping oil. I'm not exactly sure which seal is the culprit, as I've never been so inclined to take it apart beyond a basic air sleeve service. I take it in to my friendly service guy who fixes it and jokingly grumbles at me for riding too hard on basic/old equipment. I struggle to believe I'm the only one that's had this problem. Anyone care to offer any advice? I know o-rings come in different durometer seals for different conditions. Is this something worth looking at? I guess if it's a specific seal design my chances of finding something suitable or slim to none. Am I doomed to repeat the mistakes of Nasa (ref: Challenger disaster) for ever more?
