According to the product specialist

Pros
Same rim as the more expensive Shimano Dura Ace C50 rims.
Steel body, so the cassette won't bite into the body.
Combination of a deep section carbon rim and the stopping power of an aluminium rim.
Fitted with a wider rim than the previous version, meaning 25 mm tyres now sit nicely on the rim.
The wider U-shape is more aerodynamic than the V-shape of the previous model.
One of the few deep section rims with an aluminium brake track.
Cons
The deeper rim makes the wheel heavier.
