Dammit Garbage, I think your talk about busting bb bearings on install has cursed me.
I'm fine tuning and setting in the various moving parts on Bet Lynch after riding for a while. "Dialling my bike in" as the kids like to say.
I pressed my BB bearings in in the usual way, with my bearing tool and all the trimmings. But one of them feels a bit clocky, and when I'm pedaling hard it's noticeably notchy and clicky.
So I took the bottom bracket out. And sure enough one bearing pack was stuff and notchy.
Hmmmm
I have a limited store of bb bearings, so I just used the junk redline frame and some old bearings to have a practise run. To see what I might be doing wrong or forgetting to do.
Cleaned out the Chambers with a light burnishing brush head, went with Copperslip to guide everything in.
Wound the bearings in, easy, effortless, straight in and squarely bedded.
Great.
Checked them for rotation...
Like turning the cogs of a grandfather clock dredged up from the Titanic.
What the actual? That was a perfect install, and although the bearings were old/used, they felt almost perfect before the install.
