One of the main reasons was because we could then loc-tite the pulleys on to the wheel assembly easily and get a strong enough bond to not need anything else. Chain would have been a bit more of a pain to do that with.
As stated in other places, we have had good experiences with timing belt in 2010, and wanted to get rid of more chain.
We are looking at making a couple of minor tweaks to this design to make it easier to swap wheels, move the encoder to the center wheel/last reduction, and maybe make it lighter. This design served us pretty well this last year.
