So for the first time I'm working with a frame that has a PF30 BB. As I don't have the tool yet I had that pressed in by a LBS. I then put GXP reducer cups in there following the instructions provided (PF30 dust seals>GXP cups>GXP seals>wavy washer on NDS). As seen in this video in the link below, the crank actually seems to spin about what I'd expect, could be a bit better, but there is a pretty significant noise when it spins. Honestly the video exaggerates it a little bit but still... I've been doing a ton of research as I'm new to reducers, and honestly I would much rather just rock a 30mm crank but don't have one at the moment, but can't identify exactly whats causing the grind. I'm thinking maybe the BB or the reducers aren't lined up perfectly, like something at some point is slightly misaligned so the actual spindle is rubbing inside the shell? I would like to think the BB was pressed correctly so my best guess is the drive side reducer, but with a decent amount of grease I would imagine that would find its place no problem, and it looks flush to the shell all around. The NDS reducer is not flush to the shell but it doesn't go any further into the PF30 cup. Am I missing something here?
Thanks!
