It's easy and relatively cheap to have a spare 2-speed wheel and swap it in for a lighter weight bike for flat terrain.

Is this true for the current 2013/14 models? If so, has anyone done this?

I mean, the weight-savings from a 2-speed is undeniably useful for day-to-day multi-modal commuting while the 6-speed can be used for when I plan to do a bit of touring or longer distances.

I'm not that technically proficient but I would certainly put in the time and effort to learn how to switch and maintain wheels if this works.
