Well, looking closely at this frame I would doubt that the steel in the frame ever approached "Cherry Red" from a heat index scale. If that had been the case then all the alloy parts should have turned into a puddle of molten aluminum. However, the stem shows no signs of this level of heat, and did not even start to bend. the handlebars, most likely thinner and more of a pure aluminum composition, did break off. Same with the pedals, but the cranks are still mostly there, so the fire may have approached the 660C level, but most likely not 750C, or there should be nothing at all left of any of the alloy parts.
