An excellent choice for off-road 29" tandems as well as on road for very heavy tandem teams and multi-seat tandems, i.e., triplets, quads, quints...
However, at 650g it's decidedly over kill for most other teams.
The Dyad (480g @ 24mm wide) is a good choice for the average size to large tandem teams who won't run tires under 25mm. Same width as the Chukker, but 3/4 the weight.
The Deep-V (520g @ 19mm wide) is a good choice for light to middle weights looking for a more performance oriented rim who won't run tires larger than 28mm.
The Fusion (475g @ 19mm wide) is a good choise for light weight teams looking for a very light but still durable performance rim who, like the Deep-V, won't be running tires larger than 28mm.
Again, one of the things that makes Velocity rims great is the incredible variety of rims they produce, e.g., the following are just for 700c
