DZero Aluminum Power Meter Crankset Package - GXP by Quarq
We'd like to take credit for the key technologies at the heart of the GXP-compatible Quarq DZero Aluminum Power Meter Crankset Package. We'd like to, but we can't. Quarq contributed a decade of R&D to the DZero chassis, updating its already impressive accuracy with a longer battery life and even more reliability in changing conditions. All we did was pick out a pair of chainrings to mount on it. So if you like one of the three gearing options, well, you can thank us for that; however, if your true appreciation for the DZero lies in its virtually peerless accuracy while measuring watts, we've got to pass on credit to where it's due. 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 SRAM's Exogram carbon and 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 Quar...

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.
