Product Description
DZero Aluminum Power Meter Crankset Package - BB30 by Quarq
Quarq's BB30-compatible DZero Aluminum Power Meter Crankset Package is the result of two forces coming together. The first (and most important) is Quarq, which infuses the DZero chassis with all of the power meter technology that it's developed in the last decade. The second is us, though the only credit we can claim is that we picked out a pair of chainrings to mount on that chassis. While our own contribution may be humble, the amount of R&D Quarq has dumped into the DZero is staggering. The only omissions here are the use of alloy instead of sister-company SRAM's Exogram carbon and the loss of BB386EVO compatibility, which Quarq reserves for DZero power meters with Exogram carbon crank arms. Of course, the fact that this model features the more humble aluminum crank arms brings it more easily within reach of the self-sponsored cyclist, proving that there is power in humility. Those omissions aside, the list of included technologies is an all-inclusive romp through Quarq's feature menu. Chief among these is the power meter itself, which saw a healthy amount of retooling. Overall, Quarq claims that "150 documented improvements" inform the evolution from the previous models to DZero, but the most important is to the heart of the meter itself: the strain gauges and measurement circuitry. It still incorporates five strain gauges strategically placed throughout the spider in order to measure the Newton meters you're throwing into the pedals. It's also still got the same claimed accuracy of +/- 1. 5%, so its numbers are 0. 5% more accurate than most meters, but the new design requires less correction in order to maintain accuracy in drastic temperature changes. Fewer corrections mean the DZero also better rations battery life than Quarq's previous power meter models, though when the battery does go out, you can still change it without tools or having to ship the whole thing to the manufacturer. DZero's accuracy is further boosted by the return of Quarq's 10k ...

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
