• Need a Bottom bracket and can get a good deal on a model with angular contact bearings. Is this beneficial over standard bearings in a BB?

  • Someone will probably correct me on this, but I believe that angular contact bearings are only useful in a situation where significant preload is applied to the bearing.
    As with most bike bearing stuff, we don't apply enough force or spin them fast enough for it to make any noticeable difference, so get the cheapest ones with the best seals, and repack them with marine grease
