Here's the situation:
I bought a complete bike (Titanium frame) from a large chain store just over 2 years ago. On purchase, I sold the forks and immediately replaced them with a brand that I prefer.
Since then, 2 of these frames have failed on me. The first one was replaced under warranty, the second one they refuse to replace. The shop admits that it is a manufacturing fault, but they said I voided my warranty by splitting up the bike. They won't listen to the argument that all bike parts are pretty much expendable and even if I hadn't sold the forks, I could have had to replace them by now anyway.
They say the issue is that this particular frame is discontinued, but they are offering nothing more than saying I can take it up with Trading Standards if I want to.
So, does anyway know what the legal situation is? I'm going to have to spend a load of time researching it, but pointers might be helpful!
