Ruh rohh!
At least he didn't have clips! Once I was following a guy down a mountain. He was on a full suspension with clips, I was on a hardtail with flats nipping at his back tire. He went OTB, full Scorpion, with the bike smashing into his back when I hit it, because cantilever brakes just don't. He literally had to pull his chainring out of the back of his thigh where the teeth had dug in. He only laughed at RockRat in the parking lot
before the ride...
