I just purchased a used bike recently and I am curious to the make of my handlebar stem. Would anyone be able to identify the brand logo? enter image description here

I believe that's the logo for Dyno which was acquired by GT in the '80s.

This image seems to confirm that it's Dyno:… – amcnabb Oct 10 '12 at 18:09
Awesome. I hunted around a bit for an image to confirm that but I guess their logo evolved a bit over time because I couldn't find anything that quite matched. – jimirings Oct 10 '12 at 23:18
+1, not for knowing it was Dyno (who sponsored the nicest person/rider you could ever met, Dave Volker) but that they were taken over by GT too!! – BillyNair Oct 11 '12 at 20:22

It's either Dyno, or Diamond Back.
