What has happened to this thread?
Problem with quality replacement bearings is that they cost most than a new bb. And they won’t keep out mud and water any better so nuked quickly when used as bb.
Track how long your bb last, see if spending more makes sense financially.
I’ve been happy with my ck. Cane creek has some new ones that might be great - anyone tried them?
Ok maybe I need to clarify.
I KNOW what makes for a quality cartridge bearing is:
A) materials used/alloys etc that is used to manufacture the races, treatments, coatings, bearings, seals, retainers, etc.
B) the ABEC rating is a way to quantify the bearings quality or lack there of, how round the bearings are
C) Seal material placement and number of seals, along with quality of manufacturing and quality control
D) Quality standards and quality control of the unit as a whole
E) Also the receptacle that the bearing is going into is important also.
F) Almost forgot GREASE quality and possibly zirks to fill with grease and push water out, or a way to get old grease and unwanted stuff out and new grease in.
