I've read a few things.
- Buy an expensive external BB that's fully serviceable aka King
- Buy a much cheaper Shimano XT BB and just replace it in a dozen years or so.
Anybody have opinions for external vs. internal BB bearings on a commuter? Technically the external ones are "tougher" while being lighter due to using bigger bearings and a hollow shaft, but are they good for long term? Do I really need external ones? All of my other bikes have internal bearings on the BB.
You need to decide what crank you are going to use before the BB, as the crank will decide which BB type your going to use.
For serviceability vs longevity, how may XT BB's can you buy for the price of one CK? also if a Shimano MTB HT2 crank, they often come shipped with a BB included.
