Funny thing happened to me on saturday...
I was riding to my aunt's house near Brussels and there was a tough constant headwind coming from the east that day.
The whole trip is about 25 miles and it's a long and open road ... I could see the flags of the companies by the side of the road waving rapidly in my direction.
It's difficult to judge the speed of the wind while riding a bike but it seemed like a very heavy wind ... I was pumping the pedals like a madman to even maintain a speed of 13-15 MPH.
Arriving in Ninove after about 10 miles I was completely wasted and decided to take a short break and get my breath back ... so I was sitting on a bench in the local park, drinking some water ... when suddenly I noticed ... that one of the springs on my rear V-brakes wasn't attached and so the brake had been pressed against the wheel all this time!
I had just completely washed my bike before driving out and apparently it had come off.
You can imagine I felt like a complete idiot
The rest of the drive was a lot easier although the headwind did still slow me down quite a bit.
