I have had two sets one survived a season and then some (ran over some pedestrians on my way home still true) non machined brake surface eh oh well get good quality shoes the tire bead portion of the rim is a little thicker and more durable than the deep v the deepv has a problem where they dent along the braking surface near the tire bead just thin aluminum the weinmanns are about 30 a set and weigh a little more and are more durable and in my opinion the solors look better the velocity's as well
