Quoted message said: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.
Or fillet-brazed. Neither the top or down tubes are round at the ends, so they wouldn't fit lugs,
anyhow. I guess there were lugs made for Columbus Max, so it could be done (not likely).
Quoted message said: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.
Only the DT is larger (~1.5" OD, slightly ovalized ends) than available OX Platinum tubes. The main
tube wall thicknesses are similar in the middles, but the S3 tubes are thinner in the butts (ends).
The S3 seat tube and stays are small (normal) diameter with thin walls. See:

I'm having a custom sloping TT road frame fillet-brazed out of S3, which has a 1.5" downtube, with
an OX Platinum HT (S3 is too short) and 1-3/8" TT (also 0.4mm walls). The seat tube and stays will
be S3. I rode an all S3 Waterford R33 briefly and thought it was plenty stiff enough in the rear
end, so I think this'll be a good combination for me (6'-3", 185 lbs). I'll be interested to see how
the weight comes out, should be under 4 lbs, which would be pretty good for the equivalent of a 62
to 65 cm steel frame. Under $1000, too.
