So your SRAM crankset's spindle's too short for the Shimano BB is what you're telling us?
Those two pics leave me wanting more info about the BB itself... can you take then post a pic showing the BB's rim with what text it bears easily readable?
Maybe a link to the eBay'd SRAM crankset you bought as well? Where'd you acquire the frame, and whose design izzit?
