Anyone ever done this? I was looking at some of their hard tail frames with the XT/Avid Disk kit, and perhaps marzocchi fork. This seems great because I can pick out the components I want to build it from, but I would have to buy it with out riding it. Also they dont seem to have a huge selection of frames. And many of them are only available in odd sizes. If you have done this how did it work out for you? Is this a good idea?
