The Velocity is a very robust rim that is well suited for tandems that will run mid-width tires with average to above average weights. Many of the other popular rim offerings often times win out on weight, width, or other features that are attractive to teams looking for sport / performance wheels or, in the case of the Dyad, a very robust touring rim that will handle very large tires vis-a-vis the wider bead seat and higher spoke count.
