As mentioned (and slightly buried) by the article, the really fascinating part is that we already have consumer bicycle gears that deliver 97% efficiency: a Dura Ace groupset is expensive compared to the stuff you'll get at Wall-Mart, but they're sold at pretty much every cycling store. I wouldn't be surprised if the Ultegra and 105 (Shimano's next two groupsets by price) were nearly as efficient as well.
2% is nothing to sniff at in cycling (people pay thousands of dollars for that kind of advantage), but there are other factors as well: resistance to stress (sprints), ease of maintenance and service, and weight all factor into the utter dominance of the current groupset design. It'll be interesting to see if CeramicSpeed can advance their design on those fronts.
