Back in the late 50's to early 60's everyone wanted a big one, handlebar stem that is!. The fashion was for very long handlebar stems fitted with South of France type bars. We looked like kipper's hung out to dry when riding. Seriously I have one of these now very rare steel 8" steel Titan stems for sale in very good condition $75 includes shipping. I can also supply period correct type bars to match at extra cost.
Best wishes and be lucky. Michael Butler Huntingdon UK.
