I'd rubbed them with vinger then ridden half-a-dozen laps on the Cote D'azure - but obvious not enough. I was riding by myself to scrub a bit more, but caught a group and didn't fancy going even higher - slowed to their pace and slid down the banking. In hindsight, either picking up the pace & going higher, or diving for the bottom of the track when I started to slide would have probably both saved my bacon...
Yeah it's good to go over them with a bit of sandpaper before the white vinegar.
