Strengths: Light weight, Smooth Bearings, Extreemly fast wheelset, High quality spokes.
Weaknesses: Breaking surface on carbon rim has some soft spots making for some pulsing during heavy breaking. It may improve after more miles.
Bottom Line:
These wheels are fantastic for the price. They are extreemly light and climb incredibly well. The bearings spin smooth and fast. I have only about 100 miles on these wheels so far but, they are a great upgrade to your stock training wheels.
