Hey Geo - thanks for the encouragement! I'll see if they fit when I get my hub

I am using a stock Avid BB7 kit, with the included 160mm disc. In the winters it is vastly superior to rim brakes. In summertime the braking is also fine, but I find on long descents that I use my rear rim brake a lot. Mostly because I get chicken when I can smell the heat coming off that front disc!
