Pros	Affordable, easy to install, and excellent materials quality.
Cons	Internal bearings susceptible to moisture.
Verdict	Again, the key to these types of bottom brackets is proper care & drainage. Drilling drain holes into the BB shell on the bike is one way, as is to avoid spraying water directly at the seals when washing the bike. Otherwise, this component is appropriate for everything from XC, to Freeride, to sunset-chasing All-Mountain, to recreational downhilling. Strength is a non-issue, as is durability; as long as proper care is given. Any type of internal bearing bottom-bracket should never be put away wet.
	Recommended for: Anyone
