Strengths:    Price. Having said that you get what you pay for.

Weaknesses:    After less than a year of riding the free hub body cracked in half. The cassette kept everything together long enough for me to get home... You need 2 17mm cone wrenches/spanners to get at the bearings for maintenance which is normal and easily done. But you need a 15mm allen key to remove the free hub body. Shimano sell one for $50. $50?
Many have had problems with this free hub body. The XT and Saint versions of this hub have similar issues.


Bottom Line:   
Other manufactures seem to do a better job with 12/135mm and 12/142mm hubs. Unless Shimano have made improvements to the new stock, I would recommend not buying this hub.

Strengths:    10mm thru bolt capability
price


Weaknesses:    freehub body broke quickly

Bottom Line:   
I selected this hub for two reasons, 10mm thru bolt capability and price. I laced it to a 26" Stan's Flow Ex and installed it in my 2011 Stumpjumper FSR Evo. It has decent engagement but after approximately 150 miles of use, the ratcheting sound from the freehub body mysteriously changed from a light "click' click" to a raspy, unhealthy sounding click/grind noise. I pulled off the Shimano XT 9 speed cassette and discovered that the freehub body was cracked in two places. It never failed but I stopped riding it until the replacement freehub showed from Shimano. The freehub body is steel so I was very surprised that it broke so quickly. I really like the rear end feel offered by the 10mm thru bolt but I'm in the market for a different 10mm hub.
