Hey Retrobike crew,
I’ve been restoring a 1998 Specialized Stumpjumper M2 Pro trim and came across something curious: a stamped “N” on the bottom bracket shell, clearly applied before paint. This glyph isn’t part of the serial number, and it’s not referenced in any catalog or retail...
This pdf shows changes from the very early parts up to about 1998.
The document will get added content as I get more information.
This is a updated version of the previous v1.3
