Just to be clear, is the P2 a carbon or aluminum model? Is the equinox 7, this one: http://www.trekbikes.com/us/en/bikes...chive/equinox7 ?

The reason I'm clarifying is that the Equinox 7 wasn't sold in 2011; the aluminum models were 2010 holdovers while the SC 2.5 was being readied.

The other thing is that the P2 used to be an aluminum model and now is a carbon model.
