i won’t do this justice but here goes:
so i'm flyin' down this hill yesterday and out of nowhere my back wheel locks up. no, i was not braking. mentally, i've decided that a wreck is imminent and i brace for impact. it never comes. i just keep skidding like i used to as a kid on my bmx bike with a pedal brake. i eventually come to a stop and jump out of the saddle in time to see the tube which has been pinched off by the carnage pictured below, expand and blow. kaboom! fortunately i was just a couple miles from home and as i hoisted my steed onto my back a good-sam in a pickup stopped to give me a lift.
the guys at the lbs were shocked and amazed. the rim is only 3 months old so they are saying factory defect. so, i got a new wheel and tube for free. the dear wife picked up the bike today and brought it by the office so i'll be making my 12 mile ride home within the hour.
only concern now is where the tire locked up and skidded along the asphalt, the tread is exceedingly worn there. looks like new tires for christmas!
