The favorite wheelset for my terrain (stole the front for a FG century recently) is a low spoke count AL/CF composite 16X20 Shimano RS-81 running supple 25mm tires.

A single "quality" 650B rim seems to be ~500 grams vs my entire wheelset at 1,500.

Don't try to pitch: "Wheel weight doesn't matter" to an old retired racer.
It most certainly does for me, on my terrain, at my pace and in the company kept.

So, what's state of the art in wheels to get a weight below '70's touring bikes for those interested in considering 650B for a trial?
