When manufacturers talk about double/triple butter; what does that mean?

It's the number of different changes of wall thicknesses in a tube
Double butting is thick, thin, thick
Triple is thick, thin, thicker
Single is thick, thin
Etc
Stupid bloody phone. That's supposed to be butted.
Damn and I was just about to put up a Fawlty Towers "too much butter" pic 🙁
Bloody hell you lot are quick.
Thanks. Now i understand.

That's what the ladies tell us...................
Triple butted is what brant says, not what rosarch quoted (from what I've been told)
I've also been told that a frame with a "double butted" sticker may only have the tube on which the sticker is placed as double butted!
531 used to clarify this by saying butted tubes forks and stays if it was all pucker stuff
Seat tubes are rarely double butted. Single butted common.
Butting can be internal or external too.
Hard to bend butted tubing too. So bent rear stays often plain gauge unbutted. Whilst straight stays can be butted.
double buttered

brant have you held a tape measure to the bb of a 26" gaupo yet? 🙂
Smiff. In China now. Meeting with Kinesis the El Guapo manufacturers in Taiwan last week.
We have a couple of frames heading over there right now to check issues and another batch in production which will be jigged tooled and qc'd beyond their highest usual standards.
