Asymmetric Rear Wheel

New-to-tandems for 48 hours (99 Burley Duet in really fine shape) and in the clean up and maintain stage. I saw something with the rear rim that I have never seen on a single bike-asymmetric drilling. The rim is the original Bontrager Fairlane drilled 48. I'm guessing the asymmetric drilling minimizes or eliminates dish to make already strong wheel even stronger. I haven't seen any asymmetric rims on the market in my limited searching. Is this an abandoned practice?

Bontrager have historically use quite a lot of asymmetric rims. DT Swiss certainly still sell some, the RR411 and RR460 are both available in a asymmetrical version. Shimano also use asymmetric rims on some of their road wheels.

It's a sensible technique to give the right side of the rear wheel more of a bracing angle and to make spoke tension more even on the two sides.
