So which of your high end sets of wheels were these and had you any inkling of a problem previously?

As you later became aware- a problem was about to rear its ugly head and just glad that you had the skills to control the bike when the fault reared its head. Even better that you haven't lost points in the race for 2nd- but we need you to improve your mechanicing skills before the next race. I hear DG is looking for some part time work so might be able to help out in the pit crew.
