Have a few questions about Tange Tripled butted MTB tubesets. 1. Does anybody know the thicknesses?
2. When a frame is Tange triple butted will it always be all tubes, or main triangle or...? Any way to find out if no stickers indicate it?

3. How does the MTB triple butted compare in material, thicknesses and weight VS the Tange 1 through 5 types?

4. Would triple butted in theory mean the middle of tubes is very thin hence prone to denting?

5. Is it true that the old MTB Tange sticker color (the bright pink, green, yellow etc) were used on stickers regardless of butting count? It seems like see stickers in every color that say everything from just butted to triple.. I mean this type of sticker:

Reason i ask, i found a really nice Corratec Frame/complete bike (50 euros) that i plan to build into my world tourer. Only sticker it has is the one above, except it says triple butted. So i have no idea if it is whole frame, main triangle or just one tube that is triple butted... The sticker is placed high on the downtube. Which at first made me wary that it was fake. But i have seen several Corratecs with that sticker placement... Thank you!

Triple butt means the Butt on one end is different than the Butt on the other end and of course thicker than the middle ..

double butt means the 2 Butts are the same , and still not as thin as the middle.

only way to measure wall thickness now, finished frame.. is cut up the frame.

builders have the tube mill catalog specs they buy the tube set from. printed on the box..
