Concept Bikes & Bike Innovation - for better or worse

Did you not see the testing they did? He went up a grass embankment.

But seriously, they seem pretty decent, depending on how well they stay on. They are certainly identifying a real issue and their idea isn't too bad.
Weight doesn't even seem too bad, though i don't really know much about it. This struck me as impressive though I'm aware they may have chosen some of the heavier wheels for the comparison.

For comparison's sake, our 90mm wheels are within 20 grams of the shallower Zipp 808 Firecrest, and our disc wheel is nearly 150 grams lighter than a Zipp Super-9 Carbon Clincher Disc.
