Hi there

I wonder if there is anybody out there that can help me.........

I bought a giant defy 1 over a year ago( so the warranty has expired) in that time I have replaced the bottom bracket 3 times and it has just gone again I am not sure what the problem is?

So is there anyone who might know what the problem Is and how I might go about fixing it?
