Thanks for everyone's feedback. You've basically made the following clear:
- My current BB and crank setup is a-ok.
In response to my comment on a PhilWood cog for the new setup, I assumed PhilWood free/fixed track hubs would use the same cog on either side, and that one side of the hub would have an internal freewheel (rather than requiring a freewheel cog). I was also reluctant to run a freewheel-cog on my Ellipses as I doubt they were ever intended for use with brakes. Ex: They don't have wear indicators. I'd hate to have something go wrong with them from running a brake on them. (I've already been running fixed with full brakes for ~6 months, so not worried about the paint beint removed).
