How long is the life expectancy of a 90's carbon fork?
18-28 years 🙂
Seriously, there is no fixed time limit. Depending on the original quality of manufacture and the use and storage conditions, it may become weaker over time and eventually fail under normal service loads. In the worst case, it would already be broken, but then you probably wouldn't be asking. In the best case, you're not even half way through it's life yet.
Which storage conditions would be hard on a carbon fork?
UV exposure and/or elevated temperature are the likely ones. High neutron flux probably wouldn't do it any good either, but most sheds don't suffer from that :)
