Does anyone out there remember what the stack height was for a Tange G Master headset? I have a 1987 Schwinn Cimarron LE that had this headset on it (in the J.I.S. standard no less) and I need to replace it with something with a shorter stack height because the G Master only grabbed about a thread on the lock nut and I didn't realize it until recently when I decided to rebuild the bike. I was thinking of a Tange Levin, but I don't know how they compare in height and I can get absolutely no info from my local bike shop. Thanks.
