Rotated the tires on my Jake last night - I've managed to wear off most of the center tread on my rear tire. The front was fine. Decent ride in this morning - Made good time (as compared to, say, an asthmatic chihuahua.) I was waiting to turn left on a fairly quiet 4 lane road when a motorist pulled up next to me, rolled down his window and said, "That LED light is great! You can see it a mile away." Since I have 5 LED lights facing rearward, I asked him which one, figuring it was the Planet Bike Superflash on my rear rack. It was.
