The DZero's spider has been optimised for compatibility with more bikes and will now work with BB386EVO (except for the models with forged aluminium cranks), as well as all the other bottom bracket standards that previous units have worked with. MTB cranksets are now available in Boost spacing too.
Most exciting however is the new power meter's interface with Prime power ready cranks, which will come stock on bikes from Trek, Fuji, Canyon, Felt and more in 2017. The Prime crankset allows the DZero spider to be installed via an 8-bolt contact point to the crank, with the idea being you can buy a bike and a power meter at the same time and have it installed before you leave the bike shop.
The new power meter still takes its measurements from the spider and also sees Quarq's 10k temperature compensation, which means thats there’s no need to recalibrate if the temperature changes. There's also AxCad, which allows the power meter to determine cadence without magnets and take left-right power readings from the spider, and OmniCal for changing chainrings without compromising accuracy. Battery changes can be made without tools, too.
