I had one of those brown pants moments today. About halfway across reefton spur heading towards Marysville when the back wheel decided to try and beat the front wheel round the corner. I was rolling through the corner with the throttle just off closed and just about to get back on it when the rear stepped out enough to cross the bars up and then try and highside me when it grabbed again. Luckily I managed to stay on it and by the time it all straightened up I was back on the straight and hadn't even crossed the white line. The way the back let go made me think I had hit a greasy bit of road so I went back and had a look but the bitumen was dry and clean, checked out the rear tyre and it looked normal too. I wasn't going insanely fast and I can't ride off the edge of the tyre so should have had plenty of rubber on the road. To have it let go like that (it just snapped out and then gripped again) really put the wind up me and it took another 150kms before I was tackling left handers with any sort of confidence and it still felt loose and scary. I've checked the whole rear end out and everything seems in order so I'll have to put it down to my head being done in by such a near miss. On a bright note there were only 2 very short sections of roadwork on the black spur so i used that nice new bitumen to help rebuild the confidence.
