Eden has given you some great advice! No TT equipment required for this. I find that in the act of standing to climb, I actually LOSE speed, and then pick it back up. It goes down again when I sit back down. If you can maintain speed in a seated position, I would suggest that. HAve you considered a bigger gear ratio for this part of the stage race to give you enough gearing?

Good luck, and be sure to post your race report!
