I have hope bb’s and rf cranks on both my bikes on one perfectly quiet,
the other needs the cups removed from the frame every few months and
the threads and bb shell cleaned up and regreased then quiet again!
Other bb’s rf etc dont creak in it only the hope ones( have tried both
bb’s in the frame and both creak,ti frame?),only difference i can see
to other makes is the lack off thread lock.
Should also say dont actually use grease,use copperslip and assembly paste!
