Thanks for your insight. I don't know how you could figure that our from the pictures. Maybe it was my concussion, but I couldn't seem to figure out what happened.

The fourth picture of my bike clearly shows the stick, fender support and a spoke intertwined. If I hadn't had a fender the stick might have broke or popped back out.

I still don't understand how the stick got in there in the first place. I didn't see the stick at all. I have a very bright front light and I was on a wide side street that is in perfect shape. There isn't even trees hanging over the street. I have streets on my route that are covered in sticks and branches. I am going to go back there and have a look around again, but it is generally a very clean street.

I am am recovering more quickly than I thought I would. I went to physio before I took off to Hawaii and he gave me some exercises to do so maybe that is why.

Looking forward to riding again soon.
