I've been questioning the whole wisdom behind full-sized wheels ever since I started riding small-wheelers again (10/16) - so much so, in fact, that I'm trying to move my last full-sized bike due to lack of usage! I just don't think that anything bigger than 20 inches is necessary. The fact that the perceptions of the many dictate what's available to the few (small-wheeler riders) is just a shame, and something that we just have to deal with somehow.
