The Tech Zone

Welcome to the Tech Zone — the part of Vintage GT where we look under the paint. Whether you’re trying to date a frame from its serial code, work out what tubing your Karakoram was built from, or just trace how GT’s suspension thinking evolved from the RTS to the i-Drive, this is where it all lives. Browse the sections below, and if you find something we’ve got wrong, the Contribute page is always open.
