Hello again.

Sorry to come back to the group but the problem has not been sorted... I
have now ridden my lovely Giant FCR 1 for 230 miles and 190 of them have
been with this creaking noise. This is a cause of embarrassment and utter
disappointment. The LBS has 1) taken out the bb/ cleaned/greased and
replaced it....with a note stating " one cup was loose " and 2) replaced the
bb with a " better quality one " and again noted one of the cups was loose.

I manage to do about 1/2mile from the LBS and the noise returns.
I have looked at the cup and it doesn't seem as though it has tightened up
completely to the frame. i.e. you can get a fingernail between frame and
cup.

I am wondering whether there has been damage to the bb thread on the
assembly track. I also see there's alot of welding around this
area.......Do frames suffer from unseen cracks?

This noise shouldn't happen with a £500 bike which has Alu 6061 frame and
Shimano Tiagra components.......or should it?

My twelve year old Claud Butler Pagan MTB is very quiet in comparison.

Should I be thinking Sale of Goods Act now?

Thanks for your help.

Mick
