@JoeyBike, you are one monster cyclist!
I don't like that kind of music except in your videos. I love your videos.
I cannot get used to using a flashing headlight. It distracts me, reflecting off stuff. That's just a matter of taste. If I die because my headlight doesn't flash, so be it.
Are you using some kind of software that displays your speed in the video automatically? I imagine GoPro could do that, but I don't know if they do.
