So far so good. The quality seems to be good. The only reason for the four stars, is the plastic dust caps. Not sure of the durability, and would like to see something more substantial.

Plug and play! Easy install and great service.

This was a snap to install. Only problem during install was during torquing one of the BB cups the edges of the grooves got marked and one chipped. The alloy material seemed soft. The silver decal is already peeling off and have not rode with it yet. Not sure how durable the bearing cups will be but bearings feel really smooth.

Tried to give these BB a good chance but they continue to fail. My last 30mm sheared off before the bearings failed this time. They are just don't have the meat for today's riding style. I give all of RF other product a top review.

You can use this to upgrade your budget mtb. Great bearing. Only wished the bearing caps were metal
