2018 Cube Reaction Pro singlespeed conversion
 

I acquired a cube reaction frame for a singlespeed conversion since it has a BB30 bottom bracket, but realized that the BB shell is “boost” 90mm wide. I have an Origin8 Rotatr eccentric BB and I’m going to source longer bolts to make it work. Does anyone have suggestions about cranks? My thought is that a fat bike crank will work but not sure whether the 100mm or 120mm fat bike standard will work. Does anyone have a suggestion? It looks like the Origin8 EBB will extend about 12mm outside the 90mm shell on both sides. For a total width of 114mm.
