The BB30a is similar to the BB30 standard, but the frame BB shell is 5mm wider on the non-drive side. BB30a system uses thin spacers and/or a wave washer between the bearings and the crank arms to take up any slack and micro-adjust the chainline of the crank.

Yeah, so I'd need to use 24mm adapters to run Shimano cranks, like I do with my Shiv? I can handle that.
