I just installed a brand spanking new MegaExo (it's one of the style where the bearings sit outside the BB shell, thus it's supposedly a lot stiffer, but also apparently very sensitive to axial loads).
The cranks, with no chain connected, do not spin freely at all. I can give 'em a nice push, and they stop spinning within a single rotation. My old square taper BB with semi-rusty cartridge-style ball bearings (you know the $15 kind) spun way better.
In reading this: http://www.velonews.com/tech/report/...s/11607.0.html (scroll down to "Faced, spaced, or both") I learned that should visit a bike shop at some point and get by BB shell faced so I don't damage my bearings, and take a little of the friction out of the system. It's pretty obvious that my BB shell *isn't* faced since I can even see paint from the frame that has dripped down onto the BB shell. No way that can be there and everything still be perfectly aligned right?
So my question: Do you guys think it's ok to ride the bike for a while, or should I uninstall the crank and BB immediately and go get the BB shell faced (or risk destroying my BB). I'm not sure how critical of a problem this is.
