Any experience with Shimano press fit BB?
I bought a used 2010 GT SRS 1 bike frame, and it has a Dura Ace SM-FC7800P BB. I don't have any experience with press fit BBs and wanted to ask a few questions before I bought any tools that I really don't need (yet).
1. I noticed there is no inner shell between the cups? Is this normal?
2. If this is normal, I figured I'd keep them in the frame since it's relatively new. But if I were to remove them, has anyone ever removed them by tapping them out or do I need to buy the shimano bb13 tool to remove?
3. Lastly, if you've had experience, how long do the bearings last and how well do they perform?
