Good point, Curt. I am sure there are ways to make a good tandem with non-OS headset and non-OS tubing. But it seems easier to do it with oversized components.

For tandems in the CR timeline, the use of oversize headsets and tubing diameters is a first indicator of quality and good ride characteristics, unlike some rather difficult to manage tandems made from single-bike componentry. A test ride, especially by a captain with some tandeming experience, usually will show deficiencies rather quickly. Ask the stoker to wiggle their arms sideways, and see what happens. On a good tandem, nothing...

Didn't Santana also provide, free of charge, a steel pipe to be inserted into the steerer tube of their non-OS-headset tandems, to hold things together in case the steerer/fork crown joint failed? I remember Bill McCready (sp?) writing something to that effect a few years back on the tandem list...

Finally, what kinds of stems did Santana use with their extra-thickwall 1" steerer tubes? (This was before Aheadsets, I assume.) The Jack Taylors use standard 22.2 mm stems, and OS headsets - the wall thickness of the steerer tube makes up the difference... -- Jan Heine, Seattle Editor/Publisher Vintage Bicycle Quarterly http://www.mindspring.com/~heine/bikesite/bikesite/
