my sherco used to do it all the time, after weeksof trying to sort it i found out it was the original kill button so changed it for a yam style one and has never missed a beat since
she did the same on the first set of rocks after she dropped off her front wheel went out of the line supposedly, i personally think he was being a complete a***!
the observer on 15 was in a world of his own he gave taddy a 5 for going into the green route, but raga a clean and they both had their front wheel in exactly the same spot.
