Strengths: The understated white on black graphics and CNC machining give it sexy good looks. A new bottom bracket seal design lasts longer than previous models. It's stiff and reasonably light weight. You have the ability to adjust chainline and to remove granny spider for use with a chainguide.
Weaknesses: It doesn't install itself. Chainring bolts still use that stupid slot on the back. Come on people of Race Face. How hard is it to use two Torx heads like e.13?
I've been running this crank on my trail bike for two full seasons now. It's one of those parts that once you set it up right, you soon forget about it, but in a good way. It's just been a super reliable crank. The CNC machined chainrings are a work of art and up shifts are quick and smooth. Also, the awesome black paint doesn't wear off like some cranks (cough, cough...Shimano). If you have a lightweight trail bike, check out the whole Turbine line!
