Of course. Just about all modern steel frames use it, but it doesn't change what I wrote above. If
you have 2 tubes that are the same diameter and one has a thinner wall than the other, the
thick-walled tube will be stiffer. It won't matter whether these tubes are Nivachrome, 853, 525, OX
Platinum, Tange Prestige, EL-OS, or whatever.
True Temper's new S3 tubing, developed with Waterford, uses an even larger diameter tube than the
"oversized" tubing. Since no lugs are yet available for this size, it must be TIG-welded. The tubing
is essentially a version of OX Platinum. The larger diameter allows them to use an even thinner wall
than OX Plat while maintaining sufficient stiffness for lightweight use.
