Crankset Compatability
The BB shell is compatable with the BB30 Standard. See http://www.bb30standard.com/ For

Bearing Maintenance
Shell bearings (KB6180/) are sealed cartridge type and do not require lubrication. Inspect
bearing condition annually (at a minimum) and anytime the crankset assembly is disassembled
or serviced. The bearings are a press t within the shell. Old bearings should not be reinstalled
if removed. Replace both bearings at the same time.
Replacements circlips (QC616/) are available if the circlips become damaged. The circlips can be
lifted from the BB groove (inset) by lifting the hooked end with a thin blade screwdriver.
CAUTION
DO NOT FACE, MILL OR MACHINE THE BOTTOM BRACKET SHELL FOR ANY REASON.
Doing so can result in serious damage and possibly a ruined bike frame.
