BDI,
I read an article on these a while ago and was very impressed ( nipples on the hub meaning less gyro effect ). I also have a Gixxer 1K, and while at Daytona this year, I visited the Dynamag Booth and checked out the Carbon Wheels they have (Stupidly Light & $$$$$). If you are not after the "Bling" of the Alpina check out the Dymags, I know they can only be 1/20th the weight (I want some).
