in the 1913 TDF Eugene Christophe broke a fork blade during a descent. now i'm not sure what bike he was riding, but i know it wasn't a trek. stuff breaks. it happens. bianchis break. colnagos, cannondales... some $5000.00 machines suffer the exact same fate as the run of the mill GMC denali.
BTW, for those that don't know the story, Christophe hiked the bike to a local blacksmith and WELDED HIS FORK BACK TOGETHER HIMSELF to finish the race.
i'm sure George would have done the same, if aluminum was as easily welded as steel.
Now, to address the die-hard trek bashers: in a couple of years, the chances are very good that you'll be bashing cervelos or specializeds with the same self-righteous fervor that you currently reserve only for trek. don't worry, though... your ramblings will be just as inconsequential then as they are now.
and in case you were wondering, i have never thrown a leg over a trek.
