I have a BB30 bottom bracket, and bought the Wheels Manufacturing shim so I can use my GXP power meter. When I used the dust shields that come with the BB30, it seems like the crank spindle isn't long enough, as if the bearings werent pressed in all the way. Is it OK to run this without the dust shields, or am I missing something?

Pictures? And what's the model of your cranks, frame and bottom bracket? –  alex Jun 13 '13 at 0:51
