    How to read a Giant Serial Number

    I'm not sure if this is the proper place to post this, but I want to know how to read a serial number on a Giant bicycle. In particular, I want to know if a date code is included in the serial number.

    Thanks in advance.

    Is this a vintage or modern bike? Got any pics?

    What is the serial number you speak of?
    Laterally stiff yet vertically compliant.

    I believe this is a mid 2000s model based on the components and color, but when I compare the components and colors, they do not match those for any particular year according to Bikepedia. It could be that this bike has had some replacement of parts over the years, the rims don't match, so other components may have been switched out as well. The serial number is stamped on the underside of the BB housing.

    I have a kronos-GX533021 (1995) and a cross option-GR4l4047 (1994) See where I'm going with this? Just decide the decade. The trek site has some codes for dating components, if that is of any help. Tig welded and vertical drops-I believe are the 90's models. Corrections are welcomed.
