Check out the Boyd options - CF and Aluminum. I've been very happy with the three sets of aluminum wheels we have in our family, one Altamont in 700c and two CCC in 650B. NOthing but good things to say about the quality and the customer service. At the time I bought them, in the height of the pandemic, they were a great value especially considering availability. For what it's worth, the weights listed for the CCC and Altamont aluminum wheels are accurate. and pretty good.

Worth checking out.
