WTB 50-60 rear carbon clincher

Needing a replacement rear carbon clincher not really concerned with brand just use them occasionally for road races. Thanks

I have a Boyd 60 11sp clincher used in a couple of Olympic triathlons. I converted my Sram 60s to 11sp and the Boyd wheel has never been used. Let me know, I can send pics

What are you asking for it
Thanks
