I have not decided if this will be rim or disc brakes.
I had hoped to find some MTB rims that would work, but have not found anything.
They either don't have a pressure rating high enough, or only 32°.

The big questions are:
1. Will 36° holes be sufficient for tandem that will not be heavy-toured?
2. Rim choices so far: Velocity Dyad or Atlas, anything else?
Between the two Velocity rims, are there any preferences?
3. DT Alpine spokes, or ??
4. Are there any reasons for not using tubeless wheels on a tandem?
My MTB is tubeless but my road bikes are not, haven't thought about road tubeless.

thanks folks
