il mio dovrebbe essere uno dei primi telai con i perni freno per cantilever, telaio matricola numero g19093 dove 19 vuole dire la taglia e 93 il numero seriale di produzione.
Copio e incollo alcune notizie che ho trovato in questi giorni da retrobike sulla gt xizang per riconoscere l'anno di produzione così se qualcuno si imbattesse in uno di questi telai riesce ad orientarsi:
Queste sulle decals in base a colore e scritte:
1991-92
-yellow (gt all terra on toptube, xizang le titanium on downtube)
1993
-yellow/black (all gt terra on downtube, xizang on toptube)
1994
-white/black/orange (all gt terra on downtube, xizang on toptube)
1995
-white/blue/yellow (all gt terra on downtube, xizang on toptube)
1996
-yellow/black/red (gt on downtube, xizang on toptube)
1997
-white/blue/black (gt on downtube, xizang on toptube)
1998
-yellow/red/white?/black (gt on downtube, xizang on toptube)
queste invece sulle sigle del numero di telaio:
ttn-prefix serial numbers are of format (ttn?????). These may be the early maurice lavoie builds, whistler bc, canada.
g-prefix serial numbers are all gaabbb, where aa is the frame size and bbb is the production sequence number of the frame, perhaps total for that size. Example: G-19177
gt-prefix serial numbers are either another year (eg: Eventually they would have made 999 of a given size and then maybe went to the gt prefix) or a different manufacturing site than the g-sn's. Example: Gt19020
gtx-prefix serial numbers are gtxccddd, where cc is the last two digits of the year, and ddd is the production sequence for that year - a much better sn format. Example: Gtx96110
kb-prefix serial numbers are kbeeffff gg, where ee is the last two digits of the year, ffff is ???, and gg is the frame size. Example: Kb995005 19
g and gt serial numbers are the only ones stamped "made in usa". Why they would not have stamped "made in usa" if in fact all the xizang frames were made in the usa (except perhaps the ttn-numbers) is a mystery. Maybe they just thought it was too obvious to explicitly state.
