I have a Shimano BB-ES25 bottom bracket and 45T crankset that was removed from a Giant-CRX City with an eccentric hub (it had Shimano Alfine internal hub gears).
They have literally never been used, and the bike they came out of has since been stolen.
Now I'm planning a custom fixed gear bike build, and hoping to re-use these parts, since I'm on a shoestring budget.
What parts do I need to use this BB in a frame that expects a standard sized BB?
Also, am I correct that, since this is designed for an eccentric hub, I should be able to use any frame for my fixie, instead of being restricted to ones with a horizontal dropout?
