Bottom Line
The ENVE Twenty7.5 (650B) AM rims are light, and have exceptional lateral and torsional stiffness, yet they offer superlative ride quality, with excellent damping and comfort qualities. Their low rotational weight makes them highly functional (and fun) while cornering and spinning, and their stiffness offers control, precision and power transition. The well-built and innovative design is extremely tough and durable, and should offer excellent long term usage, which is a good thing, since they’re brutally expensive at $875 each.
Strengths

Did I read that right $875 for a single rim no hub no spokes! Ridiculous!
Yep, they are brutal for pricing. The durability factor helps take away some of the sting…

You’re kidding, right?
They would have to last at least 6 millenniums for this pricing to be even remotely realistic.
Two years from now we’ll see four companies offering identical (if not better) products for $89.
