I learned for the first time that aluminum alloy frames are said to have a "life expectancy". This is the bike in question, my 2007 Felt Z80. It has an aluminum alloy frame. I really like it and don't want to buy another road bike for a while. But it is almost 10 years old. [![2007 Felt Z80][1]][1] From what I was told, steel frames show their degradation with rust while aluminium alloy may not show any signs at all even though it is still degrading. My specific frame is a 7005 series alloy. How long can I expect an aluminum alloy frame to last? [1]: https://i.sstatic.net/oyq1F.jpg
