Just thought I’d share these links. I’m sure we all need good sources for reference material and to better understand bikes and parts from different era’s. There’s a lot out good info out there and I welcome anyone who’d like to add anything here.
Mark Bulgier is a former frame builder and all round bike nut. His site has been a treat/pleasure for many vintage fans, especially as for the catalogues of so many frame manufacturers (most of which were provided by Richard Sachs).
Robert S. Broderick has painstakingly scanned mostly everything in the bike world. From parts catalogues to magazine articles to odd written material. Easy to scour and lose a few days and nights.
God bless the Russians A lot of great books on most every aspect of cycling available for download in PDF format. From wheelbuilding to bike mechanics to aerodynamics and training to bike fit to frame building to nutrition to … the list goes on. Invaluable … Save these to your hard drive !!!
