Designed to be used with your X-Type cranksets. Manufactured from high strength aluminum & featuring twice the number of ball bearings than our competitors, Race Face BB cups are also compatible with some Shimano and FSA external BB systems, making for a great upgrade.
• BB Cups are forged & CNC machined from 7050 aluminum.
• Features 35% more
thread engagement & thicker walls than the XC/AM BB cups for greater durability in big-hit situations.
• Massive external bottom bracket cups house 35% larger ball bearings than internal systems, yielding vastly improved durability.
• In addition, bearings feature a special “full-complement” construction. This doubles the amount of ball bearings in the cartridge & greatly increases it’s load carrying capacity.
• Bearings feature our new custom triple wiper seal to better retain grease & keep contaminants out and are factory filled with Phil Wood waterproof grease – tested & proven to extend bearing life.
• Interchangeable with select Shimano and FSA external MOUNTAIN BB systems.

Small insert of plastic that sometimes cracks.

The older versions had a small issue of cracking the lip of plastic that the cranks ran on and then generated movement but that was a few of them most are great and work well for a very long time...

Pros
Solid and smooth.
Cons
It is a bit heavier than your normal crank. The external part of it makes it a bit unique in regards to it still being refered to as an ISIS crankset, but nothing to be concerned about.
Review
This crankset is great. I would recommend it for any hardcore XC, AM, FR, DH.
