I have been using Powercranks since Feb (longest ride just over 3 hours, but miss a chunk of training with the flue), and wondered when I should change the cranks over from my road bike to tri bike and start trying them in an aero position. Also I have a P2k, which pre powercranks I had setup with the saddle in a forward position should I look to change this to accommodate riding with the cranks?

Thanks,
