I was looking at them too.
Just google it, there's a lot of forum posts with reviews opinions etc. I found one post saying the dropouts slip followed by lots saying they are fine and some stuff about the geo, I think the angles are quite steep?
I was waiting till I got paid to buy one but then on payday I found a better, used frame on here for cheaper.
Worth remembering that when they inevitably go back down in price, an On One Inbred is right around the same price and has a better pedigree, a warranty etc.
