Has anyone found ANY information on Niners website about the BB? I have a shimano crankset and it doesnt fit. Neither my dealer, nor the closest other Niner dealer had any info. They were both in shock when the standard BB didnt fit and neither did the A9C bottom bracket. SO my question is, what exactly do you use? Is it just the Sram pfbb30 to BSA adapter or do you have to use the Wheels attachments along with it? Do I also need niners CYA cups? I appreciate the help.
