Then Thursday came.
I was heading down the Southern Outlet at about 30kms an hour and a roadie went past. Curious to see how much faster he could go, I let the brakes off ,and off I went, happily matching his pace at about 40-50km an hour. From there, it all went wrong very quickly.
The bike suddenly felt like the front anchors had gone on, and a horrible grating noise sounded from the front wheel. I pulled the bike to a stop as quickly as I could with the back brakes, and took a deep breath when a quick inspection didn't seem to show anything wrong.
I set off again, noticing the electrics were dead and thinking maybe the wheel had seized, I tried to cycle on to work, but 20 metres further along it was quite clear the bike wasn't going anywhere fast. It was like trying to cycle up Proctors road in top gear.
