GB Stem Timeline

[Fat Tire Trader]

Hello,
I just got a 87 Serotta Team bike. It came with a GB stem in it, but I think that GB stopped making stems long before 87. Can anyone point me to a GB timeline, or tell me when they began and ended production?
Thanks,
Chris

Last type of stem made by GB was the"Biba"I think, I hazard (a guess) around the late 70s early 80s.

There were many GB stems - without a pic we don't know which one your is anyway!

I have four different styles of GB stem.
