Fulcrum Racing, either the 1 (2 way fit) or the 3 (2 way fit) would work for me.

Zipp 303 is listed at 1623 grams for the wheelset. Fulcrum Racing 1 is 1500 grams. There are several other Fulcrum wheels that are lighter, but not that I need for my intended use. I was confused on the 200 grams, it is only 125 grams.

My LBS has Fulcrum wheels on sale from time to time. Racing 3 list price is $1400, Racing 1 list price is $1800. There is no Zipp dealer, but I have seen Zipp 303 wheelsets advertised at $2600 CDN. Ouch.

Shimano carbon Dura Ace Tubeless are $1700 list price locally (and they go on sale), and are 1460 grams for the wheelset. You save even more without the weight of the tubes, and the Zipps aren't available in tubeless versions.
