isn't alumium just notoriously hard to weld, and steel really easy....
therefore the chance of an aluminium frame breaking (which from examples shown to me seems to only
happen around the welds), is gonna be higher
and also if mass produced aluminium frame are on the market the quality of the weld is going to be
less, and possibly make the frame more liable to break around the weld....
i remember the original Klein Attitude frames, which were £2500 before Terk bought them, with
massive tubes and welds, which were filed down to make the join nice and smooth.... and the Pace
frames using box section alumium tubes (£800 for frame alone)....do these ever break?
