Strengths:    Smooth, not overly noisy, quick engagement

Weaknesses:    Some 2014 models are prone to breaking/failing prematurely.

Bottom Line:   
This hub came standard on my 2014 Scott Genius 730. As my LBS tech said it was most likely an issue with me washing my bike so he re-greased the hub. With some quick research I realized my freehub is the issue (grinding when freewheeling when pedals are clocked at different angles). With more in-depth research I found that this line had some issues in 2013-2014 where the freehub will crack/break prematurely. I have ordered a new one since and hopefully this will solve my grinding issue.

Not a good impression for an SLX level hub though.

Strengths:    Looks nice, not terribly expensive, smooth when it works

Weaknesses:    Weak freehub body

Bottom Line:   
First let me say, I'm not a terribly strong rider, just a weekend warrior type. Also, at 175lbs, I'm not crazy heavy, so when I broke the SECOND freehub body on this hub (in 4 months' time) I was a bit surprised and will not be purchasing a replacement. Going to bump up to the XT freehub (supposedly compatible) to see if I can get something that will last a bit longer. Definitely not recommended for anyone but a recreational rider. Plus, when it breaks it can lock up the hub completely leaving you with a fixie for the return trip :( Not great for a technical descent.
