Strengths: Stiff, Light for what it is, built up easily, good value.
Weaknesses: graphics look kind of tacky.
Overall a great rim. I have the 31 instead of the 27, but the construction is the same. I felt it built and trued easily. They are not advertised as a tubless rim, but I had not trouble setting my up that way (electric tape and stans). Long term durability is still a question as I've only had these for two months. I am 210lbs and ride hard, so if there is a weakness to these, I'm sure I will show it.
I would not hesitate to buy another as they are perfect for hard trail riding at a good weight/price.
