The ENO hub is the single best component I've ever had, hands down.

To Harlot and other ENO users: what's your standard chain-tensioning procedure?

I set tension with the bike upside down, rear wheel between my legs. I get the bolts medium-tight and then use a 3/4" wrench to set tension while making sure the bolts don't slip in the dropouts. I then wrench down and I'm on my way. In practice, this takes me about 10 seconds tops and at this point I think I could do it in my sleep.
