Title: 1998 GT Pro geometry or catalog?
Post by: 20to26 on July 29, 2008, 07:00 PM

Anyone know what headtube size is on a 1998 GT Pro Series? From what I've seen on BMXmuseum it's 1 1/8 but many owners list it as 1"....

Perhaps someone has a 98 brochure that I can confirm that?

I have 1 1/8 and 1" threaded fork and both seem to fit in the heatube, but surely this bike was the newer threadless kind, although I bought this one with a 1" threaded GT fork fitted and working. But I want this fork on a '94 I'm building...

Thanks.
