I have an ebay wheelset built with these hubs. They seem fine so far. Roll nice and smooth. Rear hub pawls are fairly loud if you like that sort of thing. I do. 

does anyone know of a fatbike frame that has 197mm spacing in the rear and 100mm bottom bracket.  All the newer US frames are built like this but chinertown rigs (and maybe Salsa) use 120mm bottom brackets unless they are using 190mm spacing in the rear then they use 100mm BB.  The Fyxation Blackhawk fatbike is supposedly a generic chinertown frame with 197mm rear and 100mm bottom bracket but I don't know who is selling it (directly from China that is).  Thanks for the help.

I don't know of any. I think a 100mm BB might be too narrow for a 197 frame, depending on the design of course. The 100 on my IP-010 only clears the chainstays by a few mm. I think I'm going to have heel rub issues with winter boots. 

Early editions of this frame have a rear spacing problem. It can be overcome by running a 197mm spaced hub or using spacers and/or machining the rotor mounting area on the hub. Either way, you have to spread the rear dropouts wider to some degree to get the rotor and cassette lockring to clear.

It's true that the first run of the IP-010 and the same frame from Speedercycling have a rear spacing issue. Apparently there is a fix in the works.
