They caught my attention at the LBS. I did a little research and I really like the Stealth FCT- 45mm CF rim, weighs 1300g and costs $1315 at Beyond Bikes. I'm not ready to buy these but I'm planning ahead. Anybody have experience with these wheels?

Also, I noticed that the Stealth FCC weigh more at 1500g and costs $200 more. Why would this be?

Thanks in advance!
