I don't imagine anyone is going to actually change the cranks on their bicycles, but larger frames typically have longer cranks and will sometimes have a greater seat tube angle -- aimed at reducing the knee angles.

The link below is a pretty good sounding article.  Given that the bike setup is static from last year, I would vote for putting too much muscle into pedaling by pushing too high gears.  Increase the cadence.  New shoes or pedals?
