I love when Harvey gets out his bathroom scales!
This mirrors what I had heard: that weight weenie timetrialers still swore by their Weinmann 500s. Did someone not post a photo recent of Beryl Burton in the late 1970s still using Weinmann 500s?
When did Weinmann start producing those distinctive levers with the square cut-outs? I always associate them with Raleigh Internationals and they strike a chord as being one of the first factory-made "drilled" or holed levers. I think Internationals had these from about 1971 onwards.
