The one TK (and the rest of retrobike) will be bidding on is far superior though that said you do need to deal with the hub issue but im not convinced youre limited to Hope hubs
As for Far Superior, I say RUBBISH !!!!!!!!!
Saying that though the ebay ones a bargain if you consider the nearest similar system that very closely resemblers it, the Woodman Disco is $140 :shock:
You dont need to drill holes in dropouts for the adaptor I use, no idea where you got that from and its as good as any welded to the frame tabs as far as rigidity is concerned :?
