I know it's too late in the season to get these in time for nationals and most likely worlds, but it's never too early to get a jump on equipment for the coming road season or even next 'cross season. I'm putting together a rim purchase from overseas and looking to get the numbers up (looking for a minimum of 5 people/sets) so they can be had at a reasonable price.
The rims are 50mm deep and 23mm wide carbon tubular rims. They should weigh approx. 750 grams per set (plus/minus 30 grams). Probably going to order them by default in sets with 20/24 holes, but other options are available.
The cost per set of rims will be $275 shipped (or $250 if you can pick them up in NYC) anywhere in the contiguous 48 states (paid up front before I order them) and the approximate wait time should be 3-4 weeks, but possibly less.
They will come with a small sticker affixed for my new wheel company, but it is easily removable if you so choose. Also, if you so desire, I can build the wheels up for you using lightweight/serviceable hubs (with your choice of color) and bladed or round spokes for a total cost tbd (but likely around $600).
Let me know if you're interested. email@example.com
