One thing I have NEVER checked all these years have been the screws on my pedal cage. On the ride just before the NTU Bike Rally 2012, my pedal cage fell off, but I tucked the parts away and rode home with minor inconvenience.
Amidst the hectic week that followed, I forgot about it until the night before the NTU Bike Rally. Failing to change my pedals when I could not find my wrench, it was down to cable ties: itsy-bitsy cable ties which I could thread through the pedal cage and pedal!
And it worked, for all 169km of the ride I did that day. I carried spares but never had to use them. Pretty neat. I’ll check my pedals during bike maintenance from now on.
