Hmmm....new technology....no dealers.....no prices listed......where do you go if servicing is needed........sounds like buyers are going to be the beta testers.

Topolino has been around for about a year. I've seen one pair of wheels in a LBS. Not cheap and maybe an answer to a question nobody asked.

About 1/4 to 1/3 pound lighter than conventional wheels. Most of the weight is saved in the central mass, hubs and spokes, not in the outer mass, rims. If you are really interested in saving critical weight, you might be better served choosing lighter tires and tubes.

An interesting experiment to see what it takes to get a rear wheel accelerated, is to rig a standard cyclocomputer to the rear wheel, put the bike in a trainer and spin the pedals 1/2 a revolution with your hand. Done briskly, the speedometer will read 35~40 MPH! It doesn't take much effort to get any rear wheel turning.
