Here's the Columbus Tenax decal.



According to Columbus distributor Nova Cycle Supply, much of the tubing used by Schwinn in the late eighties/early nineties and labeled as Tenax is actually Cromor. Other Columbus tubing may also have been labeled Tenax.



Cromor was double-butted seamed chromoly, but in the drawing and butting process the seam weld became so homogeneous that it's virtually seamless.

Here are the butting profiles for SL and Cromor showing the slightly thicker wall thickness of Cromor. The SL tubeset weight was 1925 grams, while the Cromor tubeset weight was 2190 grams.
