yes, out of the bike when they are 70mm appart, while the O ring on one side is embedded correctly the O ring on the other side is not embedded, looks like it just barely touches metal, ...barely.
Pick up another O ring? How does that help? Seems like I need a longer plastic pipe?
So from what I understand at this point about the plastic pipe that connects the cups:
- it's intended to seal out water and grime
- it comes as short as the manufacturer dared make it, causing this problem to probably be a common one.
- it probably doesn't save me much wear and tear since the bottom bracket area is well enclosed anyway. (there are only two places that I could see that water and grime could enter - through the threads, and through the hole created by the screw that attaches the plastic cable guide piece at the bottom of the frame).
Let me know if any of this sounds incorrect.
Anyhow. I found one issue that could help there is a decorative/rounded/rubber/circular decal around the BB opening that is not centered and gets between the frame and the cup. Unfortunately this is only about a millimeter thick, so removing it probably won't be enough to allow the pipe to sink into the cup. However It will probably allow the cup to sit more flush to the frame. Here's some visuals.
