SPOKE FATIGUE
After about 1400 miles, I have my first actual mechanical failure - my lardy posterior and aggressive thrashing of the bike has resulted in spoke fatigue on the rear wheel. Noticed it heading down a hill yesterday when I started to get a hell of a wiggle from the back. Thought I'd buckled the wheel at first - but hadn't done anything unusually traumatic to it.
Managed to "limp home" and couldn't see anything amiss - so decided to go and see the repair man - he took one look at me, one look at the wheel and said "spoke fatigue" and proceeded to play the wheel like a harp and with finger pressure only dispatched 6 of 32 spokes (in addition to the 3 I'd snapped). So he's rebuilding it for me over the weekend.
