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.
