I was doing my first track race of the season, the cool ass mike race at encino velodrome. We were seated by flying 200. Coming out of turn 2 my seatpost slips and the nose points severely downward, i finished in 12.1. Throughout the matches it continues to slip. It is annoying me since it already has red loctite on it. The seatpost is one from the langster pro. How can I keep it from slipping because this can't happen at nationals.
