My only concern with the Topos is reliability. One of the mechanics at my bike shop told me to keep a backup set of wheels because the Topos will develop hub problems especially in the front wheel. I was actually considering selling my backup wheels which are an almost new set up Mavic CXP 33. However, based on some of the comments I have heard, I may want hang on to them.

Yes, heavy wheels are like flywheels assuming constant speed, but when was the last time you went a constant speed on a bike? I do in my car with cruise control, but not my bike.
As for keeping a separate set of wheels, yes, recommended. I also keep a second bike in case the Calfee is out of service, like it was most of this summer with various issues (nothing related to the frame though).
Still have to write up the Calfee / Trek 5900 comparison. Exec summary: Calfee is a much better bike!
