What is "6" for?
Like, "XLE XXXXXXXX with a 6 or underlined 6 stamp off to the side?
Team model?

Never knew there ever was a “6”

Re: GT Serial Number Info

I have what appears to be a 93 performer when I look at reference photos of decals/frame/sprocket but I'm having trouble decoding serial. Any help would be greatly appreciated.

Re: GT Serial Number Info

I'll read thru the 59 pages when I have a moment big_smile

G5I00524 BB stamped 18.5 TT

According to page one of this thread, it would be -

Some of the Japanese factory's stamped the serial's on the bottom bracket.
G5I2981  G for the production line. 5 for the year 1985. I for the 9th month September.

Would this be a Pro Series or Mach One...? Or is it the same frame with different components?

Thanks

Re: GT Serial Number Info

I think same frame/diff comp.


Hutch Fun Facts: All main line Hutch's with digits only S/N (no letters or baseballs) on the rear drop outs were US made and had their dropouts stamped between late '83 and '86.  Obviously the frame manufacture would occur slightly after that, even if they just threw 'em in a bucket randomly.  There is an obvious date code in that the first 2 digits seem to be the month and the 3rd digit is pretty obviously the last digit of the year running from '83-'86.

Nothing from Japan had a model stamp.  At least some, if not all, '85 Japanese Mach Ones used the exact same frame as the Pro.

I would be offended if you built a Pro as a Mach One.tongue
