Mikey, you're correct there is a seat post/top tube clamp included and it works great. It doesn't look strong but it held my ride at any angle I tried without any slippage.
4RunnerTrail, they are Industry 9 hubs and wheels. I've got them on all my bikes and will never use anything else. They engage every 3 degrees and haven't needed a truing ever, even after 4 years of hard riding by my 200lb self.
Mudcat, I was freaked out by any kind of attachment that was need to hold my rig which is why I went with a drop in type of mount that doesn't use arms to hold the bike. The last thing I want to do is drop my bike cruising down the road. Nice KHS, I rode on of those a while back an snowshoe DH park in West VA.
Hamilton, the Nomad is a sweet ride just like most everything Santa Cruz pumps out.
So far so good on the rack, I'm heading out today for a few miles in the dirt if the rain holds out.
