I can't remember all of my course any more, but surely if the Ultimate Tensile Strength is higher the material can therefore be classed, in one sense, as stronger? Even if it can't, it almost certainly means it isn't weaker than other alloys which have a lower UTS, especially given the trends shown across all the other common aluminium alloys used in bicycle frames. Anyway, this thread is going a bit off topic really, pictures have been sent to Koxx and this thread isn't doing its' chances of being replaced any favours
