Pros: Standard issue on XT cranks. Decent seals and smooth bearings.

Cons: One use only means another pair needs to be purchased if you ever plan on moving the crankset over to another bike.

Recommendation: Good external bearings. The seals do a good job of keeping grime and funk out. The bearings can be regreased if you have a steady hand and a sharp razor knife. Just be careful not to knick the rubber seals.
