I'm about to build up my first bike with PF30 so I'm scratching my head on the instructions I see for installing the SRAM PF30 BB.
Everyone says to use the bushings supplied with the park BBT-30.3 tool (Park Tool Co. » BBT-30.3 : Bottom Bracket Tool Set for BB30 and PF30 : Bottom Bracket) but looking at those bushings it seems like they are really meant for bare BB30 bearings. The concern I have is SRAM's PF30 BB has these seals over the bearings that are comprised of two pieces... a hard rubber like ring that appears be captured between the bearing and the plastic housing and a center piece that you can remove. No one mentions these captured seals, I suspect because they've been added to newer versions of PF30 BBs. Do they need to be removed before using the park bushings to press the BB? I'm thinking they need to come out, otherwise the park bushings will crush them when I press the BB but I'm also not sure they won't be mangled if I try to pry them out.
