Do the math yourself; lots of variables. Every wheel is the sum of the weight of each part that goes into it. Go to town with published data from manufacturers and users.

But, what are you getting at? You seem rather biased against this 650b "trend". If not, my mistake, please clarify.

I haven't weighed the wheels after being built (they've only been laced). They are thru axle, centerlock hubs (DT 350 and SP PX-8). Both are 32h with Sapim Race spokes and Secure Lock brass nipples. I think I estimated all the parts to total ~1850g. Subtract 300g for non-dynamo hub.

I'm not sure what you mean by "weight penalty". All things equal smaller wheels weigh less than larger ones. Tires are going to vary dependent on their intended use and quality. FWIW, the wheels I referenced will use Pacenti tubeless tape and around 50g of Orange Seal per wheel. That said, I wanted a relatively light wheelset, but not at all costs. It has a 400+g dynamo hub afterall.
