So here's a question.

Say, I am a road rider who is also a runner and want to do some Du's. Now say that I put LOTS of miles on my road specific geometry.

Now say you put me on a TT or Tri bike with vastly different geometry that uses very different muscles than I have been training with on my roadbike. I may be more aero, but am I using my muscles as efficiently?

There are some experiments referenced to this is regards to seat height. Where it took athletes time to adjust to a more "efficient" higher seat height.
