Weaknesses: Thenipples are hidden so you would have to take the tire off to true. But I haven't had to touch them and with the increase moment of inertia I don't expect to have to.
Bottom Line:
These look amazing. 28mm deep for aerodynamics and the reliability and durability of aluminum. I coasted down my favourite hill at 78 kmph, 5 kmph faster than my old wheels.
